Angle Pair Relationships Review

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. 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 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 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 are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

If angle 1 and angle 5 are corresponding angles, what can be said about their measures?

Back

Angle 1 and angle 5 are equal in measure.

Front

If angle 2 and angle 7 are alternate exterior angles, what can be said about their measures?

Back

Angle 2 and angle 7 are equal in measure.

Front

If angle 3 and angle 5 are same side interior angles, what can be said about their measures?

Back

Angle 3 and angle 5 are supplementary, meaning they add up to 180 degrees.

Front

If angle 2 and angle 3 are vertical angles, what can be said about their measures?

Back

Angle 2 and angle 3 are equal in measure.
