Question

How do you find the coterminal with the angle `-135^circ`?

Answer 1

By adding or subtracting `360^@` one can get the co-terminal angle.

Explanation:

Given angle = `-135^@`

Co-terminal angle = -135 + 360 = 225^@#

Co-terminal angle = -135 - 360 = -495^@#

Co-terminal angle = -135 + 720 = 585^@#

In general, co-terminal angle of `-135^@ = -135^@ +- 360^@`
