Question

Draw the angles of the following measures
and determine their quadrants.
i) - 140° ) 250° iit) 420 iv) 750°
v) 945º vi) 1120° vii) -80° viii) -330°
ix) -500° x) -820°​

Answer 1

Answer:

Since

1) -140° = -90° - 50°

So -140° lies in 3rd quadrant.

2) 250° = 180° + 70°

So 250° lies in 2nd quadrant.

3) 420° = 360° + 60°

So 420° lies in 1st quadrant.

4) 750° = 360°×2 + 30°

So 750° lies in 1st quadrant.

5) 945° = 360°×2 + 225°

So 225° lies in 3rd quadrant.

6) 1120° = 360°×3 + 40°

So 1120° lies in 1st quadrant.

7) -80° = -80°

So 80° lies in 4th quadrant.

8) -330° = -270° - 60°

So -330° lies in 1st quadrant.

9) -500° = -360° - 140°

So -500° lies in 3rd quadrant.

10) -820 = -360° × 2 - 100°

So -820° lies in the 3rd quadrant
