Finding reference angles practice

WebTo find a coterminal of an angle, add or subtract 360 360 degrees (or 2π 2 π for radians) to the given angle. Reference angle is the smallest angle that you can make from the terminal side of an angle with the x x -axis. Coterminal Angles and Reference Angles – Example 1: Find positive and negative coterminal angles to angle 65∘ 65 ∘. Solution: WebWe will now repeat this process for a 60o reference angle. We first draw a right triangle that is based on a 60o reference angle, as shown below. We again want to find the values of x and y. The triangle is a 30o-60o-90o triangle. Since the length of the hypotenuse is 1 and it is twice the length of the shorter leg, x, we can say that 1 x = 2 .
