Determine which quarter angle is angle A if: a) A = 179 degrees; b) A = 325 degrees;

Determine which quarter angle is angle A if: a) A = 179 degrees; b) A = 325 degrees; c) A = -150 degrees; d) A = -10 degrees; e) A = 800 degrees; f) A = 10,000 degrees

A) A = 179 °.

One degree was not enough to the size of the unfolded angle, respectively, angle A is the angle of the second quarter.

B) A = 325 °.

The angle is more than 270 °, but does not reach 360 °, which means it is located in 4 quarters.

B) A = -150 °.

A = -90 ° – 60 ° – you can expand the angle in this way for clarity. The corner will be 3 quarters.

D) A = -10 ° – angle of 4 quarters.

E) A = 800 °. Let’s remove 2 full turns and get:

800 ° – 720 ° = 80 ° is the angle of the first quarter.

E) 10000 °. Let’s remove the full 27 revolutions and get:

10000 ° – 9720 ° = 280 ° = 270 ° + 10 °. Angle A belongs to the fourth quarter.
