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.

If angle 4 is x + 15 and angle 2 is 3x - 5, how do you find the value of x?

Back

Set the equations equal to each other: x + 15 = 3x - 5, then solve for x.

What is the exterior angle theorem?

Back

The exterior angle theorem states that the measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.
