Question

on the unit circle, in standard position, an angle of which measure is coterminal with an angle that measures pi/4 radians?

Answer 1

Coterminal angles are defined as the angles which possess the same terminal side.

The given angle measure is π/4 radians.

Consider that one full circle constitutes an angle measure of 2π radians.

So if we add 2π to the given angle, the resultant will represent the same terminal side.
