Angle Measures

• When we have a transversal intersecting parallel lines, we can use angle pairs to find the measure of angles that we do not know.

• Alternate Interior and Alternate Exterior angles are CONGRUENT (=)

• Same Side Interior and Same Side Exterior angles are SUPPLEMENTARY (add up to equal 180... if you know one of the angles, subtract it from 180 to find the other)
