What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that lie on the same side of the transversal and between the two lines. They are supplementary, meaning their measures add up to 180 degrees.

What are Alternate Exterior Angles?

Back

Alternate Exterior Angles are pairs of angles that lie on opposite sides of the transversal and outside the two lines. They are equal when the lines are parallel.
