Complementary, Supplementary, Vertical, and Adjacent Angles - BW
vertical angles
A pair of "opposite" angles that form when two lines intersect.
Supplementary angles
A pair of angles that add up to 180 degrees.
Complementary angles
A pair of angles that add up to 90 degrees.
The angles MUST add up to 180
A straight line means:
Straight angle
An angle that is 180 degrees
Right angle
An angle that is 90 degrees
Vertical angles are ALWAYS
Congruent
65⁰

81⁰
Find the supplementary angle of the given angle whose measure is 99⁰.
