In which quadrant does the angle −1060° lie?

Think it through first, then pick an option.

  1. a 1st
  2. b 2nd
  3. c 3rd
  4. d 4th
Answer and explanation

Correct answer: a 1st

-1060° + 3 × 360° = 20°, which lies between 0° to 90°; so the 1st quadrant.

Why the other options are wrong

  • b 2nd: The 2nd quadrant holds angles from 90° to 180°; the equivalent angle of -1060° is 20°, so it is not this one.
  • c 3rd: The 3rd quadrant holds angles from 180° to 270°; the equivalent angle of -1060° is 20°, so it is not this one.
  • d 4th: The 4th quadrant holds angles from 270° to 360°; the equivalent angle of -1060° is 20°, so it is not this one.
