Parallel Lines and Transversals Retake

Front

If m∠2 = 55°, find the measure of ∠1.

Back

m∠1 = 125° (∠1 and ∠2 are supplementary angles).

Front

If m∠2 = 55°, find the measure of ∠8.

Back

m∠8 = 55° (∠2 and ∠8 are corresponding angles).

Front

Which angle is NOT congruent to ∠5? Options: ∠2, ∠3, ∠4, ∠6

Back

∠4 (∠4 is an alternate interior angle and not congruent to ∠5).

Front

Complete the sentence: When parallel lines are cut by a transversal, the angles formed are either __________ or congruent.

Back

supplementary.

Front

Given m//n, name a pair of vertical angles: Options: ∠1 and ∠7, ∠1 and ∠2, ∠2 and ∠3, ∠4 and ∠5

Back

∠1 and ∠7 (Vertical angles are opposite angles formed by two intersecting lines).

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to a transversal.

Front

What is the sum of the interior angles of a triangle?

Back

180°.

Front

Define alternate interior angles.

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

They are congruent.

Front

What is the relationship between consecutive interior angles when two parallel lines are cut by a transversal?

Back

They are supplementary.
