Read each question carefully and answer to the best of your ability. Use the provided diagrams to help you visualize the angles and lines.

Use the diagram below for questions 1-4.

L1 L2 T 1 2 4 3 5 6 8 7

1. Which pair of angles are corresponding angles?

a

∠1 and ∠8

b

∠2 and ∠6

c

∠3 and ∠6

d

∠4 and ∠5

2. Which pair of angles are alternate interior angles?

a

∠1 and ∠7

b

∠2 and ∠5

c

∠3 and ∠6

d

∠4 and ∠5

3. If lines L1 and L2 are parallel, then ∠1 and ∠5 are   angles and are  .

4. If lines L1 and L2 are parallel, and m∠3 = 70°, then m∠6 =   because they are   angles.

5. Explain the relationship between consecutive interior angles when a transversal intersects two parallel lines.

Use the diagram below for questions 6-8. Assume lines 'a' and 'b' are parallel.

a b c A B D C E F H G

6. Angles A and E are consecutive interior angles.

T

True

F

False

7. If m∠C = 110°, then m∠F = 110°.

T

True

F

False

8. If m∠D = (3x + 10)° and m∠G = (2x + 30)°, find the value of x.
