Example 1:
Label the quadrants
Define:
Quadrantal Angle:
Example 2:
Draw the following angles in standard position. Then classify the angle by quadrant. If the angle is a
quadrantal angle, identify it.

Go back up to the picture that identified the Quadrantal angles in degrees, and identify the Quadrantal angles in
radians. Label the coordinate axis with the radian measures as well as the degree measures.

Coterminal Angles
Example 5:
Determine the measure of the positive angle with measure less than
that is coterminal with
the given angle, and then classify the angle by quadrant. Assume the angles are all in standard
position.
