# How do you draw angles of rotation in standard position?

You can draw an angle in standard position by positioning its vertex at the origin and one "ray" on the positive x-axis. The ray on the x-axis is called the **initial side** and the other ray is called the **terminal side**.

An angle is then measured POSITIVE for a counterclockwise rotation and NEGATIVE for a clockwise rotation:

When two angles have the same initial and terminal sides, they are said to be **coterminal angles**.

Angles of −315° and 45° are coterminal angles.
