Parallel lines and transversals

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 Consecutive 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°).

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 is the relationship between Supplementary Angles?

Back

Two angles that add up to 180°.

Front

What is the relationship between Congruent Angles?

Back

Two angles that have the same measure.

Front

If ∠B = 82°, what is the measure of its Corresponding Angle?

Back

∠B = 82° (Corresponding angles are equal).

Front

If two parallel lines are cut by a transversal, what can be said about the Alternate Interior Angles?

Back

They are equal in measure.

Front

If ∠C and ∠P are Consecutive Interior Angles, what can be said about their measures?

Back

They are supplementary (add up to 180°).

Front

If ∠R and ∠C are Corresponding Angles, what can be said about their measures?

Back

They are equal in measure.
