Unit 4 Lesson 3 Self-Check: Parallel Lines & Transversals

If the blue lines are parallel and m∠1 = 135, then find m∠3.

• 45°

• 65°

• 135°

• 225°

If the blue lines are parallel and m∠6 = 25, find m∠7.

• 25°

• 50°

• 90°

• 155°

If the blue lines are parallel and m∠8 = 63, then find m∠2.

• 63° because ∠8 & ∠2 are alternate exterior angles.

• 117° because ∠8 & ∠2 are supplementary.

• 63° because ∠8 & ∠2 are vertical angles.

• 117° because ∠8 & ∠2 are consecutive exterior angles.
