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 similar positions at each intersection where a transversal crosses two lines.

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie on the same side of the transversal and between the two lines.

How do you find the measure of an angle if you know the measure of its supplementary angle?

Back

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

If angle 1 measures 27 degrees, what is the measure of angle 4 if they are alternate interior angles?

Back

If angle 1 and angle 4 are alternate interior angles, then angle 4 also measures 27 degrees.
