An angle is the rotation required to superimpose one of two intersecting lines on the other.
Two rays that have the same endpoint form an angle. That endpoint is called the vertex, and the rays are called the sides of the angle. In geometry, an angle is measured in degrees from 0° to 180°. The number of degrees indicates the size of the angle.
There are many kinds of angles in geometry.
Angle bisector
An angle bisector is a ray that divides an angle into two equal angles.
Right angle
A right angle has a measure of 90°.
Acute angle
An acute angle is any angle whose measure is less than 90°.
Obtuse angle
An obtuse angle is an angle whose measure is more than 90° but less than 180°.
Straight angle
Some geometry texts refer to an angle with a measure of 180° as a straight angle.
Measuring Angles
We measure the size of an angle using degrees.
Complementary Angles
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.
Supplementary Angles
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.
