What is a transversal?

Back

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

Front

What are corresponding angles?

Back

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

How do you find the measure of an angle when given its supplementary angle?

Back

To find the measure of an angle when given its supplementary angle, subtract the measure of the supplementary angle from 180 degrees.

What is the sum of the measures of corresponding angles when two parallel lines are cut by a transversal?

Back

The sum of the measures of corresponding angles is equal; they are congruent.
