Ch. 3 - Angle Pairs

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are same-side interior angles?

Back

Angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary (add up to 180 degrees).

Front

What is the sum of the angles in a triangle?

Back

180 degrees.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are equal in measure.
