Angles formed by Parallel Lines & Transversals (Vocab)

Front

What are the angles formed when two parallel lines are cut by a transversal?

Back

The angles formed include Alternate Interior Angles, Alternate Exterior Angles, Corresponding Angles, and Same-Side Interior Angles.

Front

Define Alternate Interior Angles.

Back

Alternate Interior Angles are pairs of angles that lie between two parallel lines and on opposite sides of the transversal.

Front

Define Alternate Exterior Angles.

Back

Alternate Exterior Angles are pairs of angles that lie outside two parallel lines and on opposite sides of the transversal.

Front

Define Corresponding Angles.

Back

Corresponding Angles are pairs of angles that are in the same position on two parallel lines in relation to the transversal.

Front

Define Same-Side Interior Angles.

Back

Same-Side Interior Angles are pairs of angles that lie between two parallel lines and on the same side of the transversal.

Front

What is the relationship between Same-Side Interior Angles?

Back

Same-Side Interior Angles are supplementary, meaning they add up to 180 degrees.

Front

What is the relationship between Alternate Interior Angles?

Back

Alternate Interior Angles are congruent when two parallel lines are cut by a transversal.

Front

What is the relationship between Corresponding Angles?

Back

Corresponding Angles are congruent when two parallel lines are cut by a transversal.

Front

If ∠1 and ∠5 are Corresponding Angles, what can be said about their measures?

Back

The measures of ∠1 and ∠5 are equal.

Front

If ∠3 and ∠8 are Alternate Interior Angles, what can be said about their measures?

Back

The measures of ∠3 and ∠8 are equal.
