Stuff You MUST Know Cold for the AP Calculus AB Exam[EVERYTHING YOU NEED TO KNOW] 2021

Most students have plenty of time to finish all the questions on the Geometry Regents exam. In fact, most students finish with many minutes leftover on the 3-hour time limit!

However, this doesnt mean you should stay stuck on a single multiple-choice question as you work through the exam. Its important to stay confident and focus on the questions you DO know really well. You can always go back to tricky questions and spend extra time thinking through different options. In fact, we often think of new ideas on how to solve tricky problems just by working on other problems elsewhere on the exam!

We generally suggest about 3 minutes for each multiple-choice question. For more details on how to pace yourself on the exam, check out our full Geometry Regents Review Guide.

If Your Prompt Says Parallelogram Think About Some Special Properties

Stuff You Must Know Cold!  Flamingo Math with Jean Adams

The definition of a parallelogram is simple enough: a quadrilateral with two pairs of parallel sides. Examples of parallelograms include squares, rectangles, and rhombuses. For the Geometry Regents exam, youll also need to remember certain properties of parallelograms:

  • Both pairs of opposite sides and opposite angles are congruent.
  • The diagonals bisect one another.
  • Each diagonal breaks the parallelogram into two congruent triangles.

Use High Quality Practice Materials

The best way to prepare for the GMAT is by using real GMAT geometry questions in your prep. Real GMAT geometry questions will simulate the GMATs style and content. For instance, youll have to use more than one skill in the question, or youll get practice using your geometry skills on data sufficiency questions, which are unique to the GMAT. Using resources like GMATPrep or the GMAT Official Guide will give you access to real, retired GMAT questions.

As you mightve noticed from our practice questions, youll rarely see a straightforward question on the GMAT that just asks you to use your geometry skills. Youll likely have to combine your knowledge of geometry with your knowledge of arithmetic or number properties or ratios or all of the above! Practicing GMAT-style questions will give you practice at using multiple skills in one question.

The Top 5 Most Common Topics On The Geometry Regents Exam

Get Comfortable With Trigonometric Functions

In the Geometry Regents exam, youll be expected to recognize, understand, and apply trigonometric functions.

There are three trigonometric functions you should commit to memory: sine, cosine, and tangent. Students are often taught to remember these functions with the mnemonic Sohcahtoa. To refresh your memory, the functions are:

  • The sine of an angle is the ratio of the opposite side to the hypotenuse.
  • The cosine of an angle is the ratio of the adjacent side to the hypotenuse.
  • The tangent of an angle is the ratio of the opposite side to the adjacent side.

Once youve figured out which function to use, your calculator can do the rest. Hit MODE to make sure your calculator is in DEGREES, and then use the appropriate trigonometric function button to solve your problem.

Regents Question

If Your Prompt Says Similar Think Same Angles Different Size

Stuff You MUST Know Cold for the 2021 AP Statistics Exam [WHAT YOU NEED TO KNOW]

We all know what similar means in everyday English, but this term takes on a whole new meaning in the context of the Geometry Regents exam. When two shapes are similar, it means they have congruent angles but different side lengths. Symbol Spotlight: Remember that the \cong symbol means congruent and \sim means similar. Congruent shapes, angles, and measurements are exactly the same, while similar shapes are proportional to one another.

It also helps to remember that when a figure is dilated, it creates a figure similar to the original. That means that it will have congruent angles, but a different size.

If Your Prompt Says Altitude Think About A Perpendicular Line

Altitude is another word that means something different in day-to-day conversations and on the Geometry Regents exam. The altitude of a triangle is a line drawn from a vertex to the opposite side such that it is perpendicular to a line containing the opposite side.

Symbol Spotlight: The symbol \perp means perpendicular. The altitude of a triangle is perpendicular to the line containing the opposite base of that triangle, which means it creates 90^\circ angles.

A couple things to remember about altitudes:

  • An altitude to the base of an isosceles triangle bisects both the vertex angle and the length of the base.
  • An altitude to the hypotenuse of a right triangle creates two triangles that are both similar to one another and to the original right triangle.

Example question:

Most Common Topic: Dilations

Stuff You Must Know Cold for the AP Calculus BC Exam!

Description: Understand dilations of a line or line segment.

Frequency: This topic has been assessed in 100% of recent exams.

Pro Tip: This topic is frequently assessed as a multiple-choice question in Part I of the Regents Geometry exam.

Math Standard: HS.G.SRT.1 // Verify experimentally the properties of dilations given by a center and a scale factor. a) A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged. b) The dilation of a line segment is longer or shorter in the ratio given by the scale factor.

Most Common Topic: Right Triangles In Application Problems

Description: Solve real-world application problems involving triangles using trigonometric ratios and the Pythagorean Theorem.

Frequency: This topic has been assessed in 100% of recent exams.

Pro Tip: This topic is assessed both as a multiple-choice question and as a constructed-response question on Regents Geometry exams.

Math Standard: HS.G.SRT.8 // Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems.

Example:

Start With Your Strengths

Some students like to read all the constructed response prompts on their Regents exam before actually writing down answers. When you begin Part II of the Geometry exam , you can quickly skim all of the questions. This might be helpful as you can find the questions you are most confident in and knock them out first.

Youll feel motivated as you begin the constructed response questions. Pre-scanning the questions will allow you extra time for the questions that will take you longer to solve. If you decide to answer questions in your own order for the exam, just be sure you answer all the questions provided.

Remember: You should never leave a constructed response question with a blank answer.

Look For Connections On Multiple Figure Questions

If there is more than one recognizable shape in a diagram, there is a connection between them. Look for what one of the figures tells you about the other. Perhaps the diagonal of a square is the same as the radius of a circle. Or the height of one triangle is the hypotenuse of another. Whatever the connection, its probably the key to answering the question.

Most Common Topic: Congruence And Similarity Of Triangles

The Most Important Gmat Geometry Formulas And Rules To Know

The good news about GMAT geometry is that you dont need to brush up on a whole bunch of topics in order to do well. The bad news about GMAT geometry is that youll have to memorize all the rules and formulas you need to know for the test, because none will be provided to you on test day. You also cant bring in any aids to help you with the exam.

In this section, Ill talk about the major GMAT geometry formulas and rules that you should study and memorize as youre preparing for the exam.

  • A line is a one-dimensional abstraction that goes on forever.
  • For any two points, there is one straight line that passes through them.
  • A line section is a segment of a straight line that has two endpoints. The midpoint is the point that divides the line segment into two equal parts.
  • Two lines are parallel if they lie in the same plane and never intersect. Two lines are perpendicular if they intersect at a 90° angle.
  • An angle is made when two lines intersect at a point. This point is called the vertex of the angle.
  • Angles are measured in degrees .
  • An acute angle is an angle whose degree measure is less then 90°.
  • A right angles degree measure is exactly 90°.
  • An obtuse angles degree measure greater than 90°.
  • A straight angles degree measure is 180°.
  • The sum of the measures of angles on a straight line is 180°.
  • The sum of the measures of the angles around a point is 360°.
  • Two angles are supplementary if their sums make a straight angle.

Make Your Own Diagram

If youre solving a question that involves a shape, but the test doesnt give you a diagram, make your own. Making your own diagram will help you better visualize a question. You can also re-draw a diagram on your scrap paper even if the test provides you with a diagram to view. Sometimes, re-drawing a diagram will help you get a better understanding of the figure so that you can more easily solve the problem.

Use The Process Of Elimination

Whenever youre presented with a wide range of answer options, it can be helpful to eliminate any answer choices that you know cannot be correct. This is called the process of elimination.

For the Geometry Regents exam, youll be given 4 possible answer choices on all multiple-choice questions. Its very likely you can eliminate at least one and maybe even two of the answer choices pretty easily. As you go through each possible answer choice, literally draw a line through any answer choice that must be wrong.

If you cant decide on a final answer, take an educated guess or try a new strategy. Whatever you do: do NOT leave any question blank on your Regents exam. You do not lose credits for a wrong answer, so its much better to just guess instead of leaving something blank.

What makes the process of elimination such a great trick?

You originally start with a 25% chance of randomly guessing the right answer . If you can eliminate two of the answer choices, that means youve doubled your chances of getting the question correct to 50% awesome!
