Angles
A right angle is 90˚
An acute angle is less than 90˚
An obtuse angle is more than 90˚ but less than 180˚
A straight angle is 180˚
1 complete angle of rotation is 360˚
Reflex angles are greater than 180˚
Two angles are called complementary angles if the sum of their degree measurements equals 90 degrees. One of the complementary angles is said to be the complement of the other.
Two angles are called supplementary angles if the sum of their degree measurements equals 180 degrees. One of the supplementary angles is said to be the supplement of the other.
