WebHow to tell if two angles are coterminal. You can sketch the angles and often tell just form looking at them if they are coterminal. Otherwise, for each angle do the following: If the angle is positive, keep subtracting 360 from it until the result is between 0 and +360. (In radians, 360° = 2π radians) WebNov 28, 2024 · Question 1: Find the coterminal angle of π/2. Solution: Given: The angle is θ = π/2. (In radians) Now, Add or subtract multiples of 2π from the angle, Let’s subtract 2π …
