Lines and angles

In the given fig, Alternate interior angles are

1. <4 and <5 , <3 and <6
2. <1 and < 3
3. <1 and <2, <5 and <6
4. none

Corresponding angles are:

1. <4 and <5
2. <1 and <6, <2 and <5
3. <1 and <3, <2 and <4
4. none

Angles on same side of transversal

1. <1 and <3
2. <1 and <2 , <7 and <8
3. <4 and <6, <3 and <5
4. None

LEARNING OBJECTIVES

               1) Identify the relation between the pairs of angles            formed when a transversal intersects parallel lines.

2) Apply the concepts learnt to solve problems

Identify the relation between the pairs of angles formed when a transversal intersects parallel lines.

Identify the relation between the pairs of angles formed when a transversal intersects parallel lines.

If two lines are parallel, then sum of co interior angle is

1. 360 degree
2. 90 degree
3. 180 degrees
4. 100 degrees

If one of the co interior angle is 50 degree, then the measure of other one is

1. 40 degrees
2. 130 degrees
3. 50 degrees
4. 100 degrees

If two lines are parallel, then the alternate interior angles are

1. not equal
2. equal
3. 100 degrees
4. 10 degrees

In the diagram, AB is parallel to CD. Then the value of x is equal to

1. 72 degree
2. 45 degree
3. 180 degrees
4. 90 degrees

Given that ∠4 and ∠6 are consecutive interior angles, and ∠5 measures 110 degrees, what is the measure of ∠6? Explain why?

Line l and m are parallel to each other.<QRP = 80 degree and <RST=35 deg. What is the measure of <QPR?

1. 20 degree
2. 35 degree
3. 65 degree
4. 115 degree
