Read each question carefully and determine the quadrant in which the given angle lies. All angles are in standard position.
1. In which quadrant does an angle of 135° lie?
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
2. An angle measuring -210° is in which quadrant?
Quadrant I
Quadrant II
Quadrant III
Quadrant IV
3. An angle of 280° lies in Quadrant .
4. The angle 450° is coterminal with an angle of 90°, which lies on the positive -axis.
5. If an angle's terminal side is in Quadrant III, its measure could be degrees.
6. Draw a coordinate plane and sketch an angle of 300° in standard position. Label the quadrant it lies in.
7. Explain how to determine the quadrant of a negative angle.
8. An angle of 0° is in Quadrant I.
True
False
