An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

Front

What are the different types of angles based on their measures?

Back

The different types of angles are acute (less than 90°), right (exactly 90°), obtuse (greater than 90° and less than 180°), straight (exactly 180°), reflex (greater than 180°), and full (360°).

Front

How do you convert degrees to radians?

Back

To convert degrees to radians, multiply the degree measure by π/180.
