Find the Reference Angle 45

Problem

45^∘

Solution

1. Identify the given angle and its quadrant. The angle is 45^∘ which lies in the first quadrant (0^∘<45^∘<90^∘.

2. Apply the rule for reference angles in the first quadrant. For any angle θ in Quadrant I, the reference angle θ^′ is equal to the angle itself.

3. Calculate the reference angle using the formula θ^′=θ

4. Substitute the value to find θ^′=45^∘

Final Answer

θ^′=45^∘
