Angles
Classifying Angles
Angle Pairs
If the sum of the measures of two angles equal 90o, the angles are complementary.
<M and <N are complementary, if m<M = 9o find m<N.
(the symbol < means angle and m<stands for the measure of the angle)
If the sum of the measure of two angles equal 180o, the angles are supplementary.
<F and <G are supplementary, if m<F = 84o find m<G.
