What is the definition of vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent.

Front

If two angles are supplementary, what is the sum of their measures?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

What is the definition of complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

How do you find the measure of an angle formed by intersecting lines?

Back

Use the relationships of vertical angles, adjacent angles, or supplementary angles to find the unknown angle.
