Find two positive angles and two negative angles that are coterminal with 60
To find coterminal angles, we add or subtract multiples of 360 degrees (or 2π radians) from the given angle.
Positive coterminal angles:
1) Adding 360 degrees: 60 + 360 = 420 degrees
2) Adding 720 degrees: 60 + 720 = 780 degrees
Negative coterminal angles:
1) Subtracting 360 degrees: 60 - 360 = -300 degrees
2) Subtracting 720 degrees: 60 - 720 = -660 degrees
Note: Coterminal angles are angles that have the same initial and terminal sides, but different measures.
