Angles in Parallel Lines & Transversals

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What is the measure of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

How do you find the measure of a missing angle when given one angle in a linear pair?

Back

Subtract the known angle from 180 degrees.

Front

What are corresponding angles?

Back

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

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and between the two lines.

Front

What is the relationship between consecutive interior angles when two parallel lines are cut by a transversal?

Back

Consecutive interior angles are supplementary.

Front

What is the definition of a transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the angle relationship between vertical angles?

Back

Vertical angles are equal.
