Pairs Of Lines And Angles

Cumulative Review #15 (Problems 1-3)

Exploration 1

Points of intersection

work with a partner: Write the number of points of intersection of each pair of coplanar lines.Answer:The given coplanar lines are:a. The points of intersection of parallel lines:We know that,The Parallel lines have the same slope but have different y-interceptsSo,We can say that any parallel line do not intersect at any pointHence, from the above,We can conclude that the number of points of intersection of parallel lines is: 0

a. The points of intersection of intersecting lines:We know that,The Intersecting lines have a common point to intersectSo,We can say that any intersecting line do intersect at 1 pointHence, from the above,We can conclude that the number of points of intersection of intersecting lines is: 1

c. The points of intersection of coincident lines:We know that,The Coincident lines may be intersecting or parallelSo,We can say that any coincident line do not intersect at any point or intersect at 1 pointHence, from the above,We can conclude that the number of points of intersection of coincident lines is: 0 or 1

Exploration 3

Identifying Pairs of Angles

b. Identify all the linear pairs of angles. Explain your reasoning.Answer:A Linear pair is a pair of adjacent angles formed when two lines intersectHence, from the given figure,We can conclude that the linear pair of angles is:1 and 2 4 and 3 5 and 6 8 and 7

Lesson 32 Parallel Lines And Transversals

Monitoring Progress

Use the diagram

Question 1.Given m1 = 105°, find m4, m5, and m8. Tell which theorem you use in each case.Answer:It is given that 1 = 105°Now,We have to find 4, 5, and 8Now,To find 4:Verticle angle theorem:Vertical Angles Theorem states that vertical angles, angles that are opposite each other and formed by two intersecting straight lines, are congruentSo,

We can conclude that the value of x is: 54°

Question 3.In the proof in Example 4, if you use the third statement before the second statement. could you still prove the theorem? Explain.Answer:In Example 4, the given theorem is Alternate interior angle theoremIf you even interchange the second and third statements, you could still prove the theorem as the second line before interchange is not necessaryHence, from the above,We can conclude that if you use the third statement before the second statement, you could still prove the theorem

Question 4.WHAT IF?In Example 5. yellow light leaves a drop at an angle of m2 = 41°. What is m1? How do you know?Answer:If we observe 1 and 2, then they are alternate interior anglesNow,According to Alternate interior angle theorem,1 = 2

1 = 2 = 133° and 3 = 47°

Question 13.Describe and correct the error in the students reasoningAnswer:

b. Name two pairs of supplementary angles when \ and \ are parallel. Explain your reasoning.Answer:From the given figure,The two pairs of supplementary angles when \ and \ are parallel is: ACD and BDC

Question 1.Draw the portion of the diagram that you used to answer Exercise 26 on page 130.Answer:The portion of the diagram that you used to answer Exercise 26 on page 130 is:

Question 2.In Exercise 40 on page 144. explain how you started solving the problem and why you started that way.Answer:In Exercise 40 on page 144,You started solving the problem by considering the 2 lines parallel and two lines as transversalsSo,If p and q are the parallel lines, then r and s are the transversalsIf r and s are the parallel lines, then p and q are the transversals

Lesson 31 Pairs Of Lines And Angles

Ch. 1

Monitoring Progress

Question 1.Look at the diagram in Example 1. Name the line through point F that appear skew to .From Example 1,We can observe thatThe line that passes through point F that appear skew to \ is: \

Question 2.In Example 2, can you use the Perpendicular Postulate to show that is not perpendicular to ? Explain why or why not.Answer:Perpendicular Postulate:According to this Postulate,If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given lineNow,In Example 2,We can observe that \ is not perpendicular to \ because according to the perpendicular Postulate, \ will be a straight line but it is not a straight line when we observe Example 2Hence, from the above,We can conclude that we can use Perpendicular Postulate to show that \ is not perpendicular to \

Classify the pair of numbered angles.

Question 3.

We know that,The angles that have the common side are called Adjacent anglesThe angles that are opposite to each other when 2 lines cross are called Vertical anglesSo,2 and 3 are vertical angles4 and 5 are adjacent angles1 and 8 are vertical angles2 and 7 are vertical anglesHence, from the above,We can conclude that 4 and 5 angle-pair do not belong with the other three
