Standard Position & Coterminal Angles

clockwise

- graph negative angles in this direction from the initial to terminal side

counterclockwise

- graph positive angles in this direction from the initial to terminal side

coterminal angles

two angles that have the same terminal side.

quadrantal angle

- if the terminal side of an angle lies on the axis (like a 90 or 180 degree angle).

initial side

- the ray on the x-axis of an angle in standard position.

terminal side

- the ray that rotates in an angle in standard position.

standard position

- which term states the vertex of an angle is located at the origin and one ray is on the positive x-axis?
