Angle Relationships with Parallel Lines & Transversals

Front

What is the Same Side Interior Angles Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of same-side interior angles is supplementary (adds up to 180 degrees).

Front

What does the Vertical Angles Theorem state?

Back

When two lines intersect, the opposite (vertical) angles are equal.

Front

Define Supplementary Angles.

Back

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

Front

What is the Corresponding Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

Explain the Alternate Exterior Angles Theorem.

Back

If two parallel lines are cut by a transversal, then each pair of alternate exterior angles is equal.

Front

What is the Alternate Interior Angles Theorem?

Back

If two parallel lines are cut by a transversal, then each pair of alternate interior angles is equal.

Front

What is a Linear Pair of Angles?

Back

A linear pair consists of two adjacent angles that form a straight line, and they are supplementary.

Front

How do you identify Corresponding Angles?

Back

Corresponding angles are located in the same position at each intersection where a transversal crosses two lines.

Front

What is the relationship between angle 10 and angle 11 if they are same-side interior angles?

Back

According to the Same Side Interior Angles Postulate, angle 10 and angle 11 are supplementary.

Front

If angle 10 and angle 13 are vertical angles, what can be said about their measures?

Back

Angle 10 and angle 13 are equal in measure.
