Recall what it means for an angle to be drawn in
standard position.
(If you need a refresher,

The applet below dynamically illustrates what it means for any 2 angles (drawn in standard position) to be classified as
COTERMINAL ANGLES.
Below, you will eventually see the formation of
one positive angle and
one negative angle that are both coterminal with each other.
Interact with this applet for a few minutes.
Then answer the questions that follow.
