In geometry, an angle is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other.

Angles in Geometric Figures
Two rays to contain the similar endpoint form an angle. That endpoint is identified as thevertex, also the rays are known as the sides of the angle. Within geometry, an angle is considered within degrees as of 0° to 180°. The number of degrees specifies the measurement of the angle.
Following are the angles in geometric figures
- Right angle
- Acute angle
- Obtuse angle
- Complementary angles
- Supplementary angles
Right angle:
It is an angle through calculate equal to 90 degrees. The degree of this angle is always less than 90 degrees.
Acute angle:
It is an angle through a compute between 0 and 90 degrees.
Obtuse angle:
It is an angle through calculate between 90 and 180 degrees.
Complementary angle:
If the total of their measures is equal to 90 degrees subsequently two angles are complementary.
Supplementary angles:
If the total of their measures is equal to 180 degrees subsequently the two angles are supplementary
