• Complementary angles are two angles whose measures have a sum of 90°.

• Supplementary angles are two angles whose measures have a sum of 180°.

• Adjacent angles are pairs of angles that share a vertex and one side, but do not overlap.

• Congruent angles have the same measure.• Vertical angles are opposite angles formed

by two intersecting lines and are congruent.

• Use the relationships about angle pairs, such as supplementary, complementary, or vertical angles, to write and solve an equation to find the unknown measure of an angle.

• Two intersecting lines form two pairs of opposite congruent angles. Also, the two measures of each pair of adjacent angles formed by the lines add up to 180°.
