WebMore Practice Finding Reference Angles. Reference angle: Given angle θ in standard position, its reference angle θ′ is the smallest positive angle formed by the terminal side … WebWe discover that the two radian angles whose cosine is 1/2 are = /3 and = -/3 using the unit circle. We know that both angles have the same reference angle since the reference angle for is 60°, or /3 radians. The two angles are as follows, measured in radians: θ = π/3 and θ = -π/3. The two angles are therefore 3 and -3 in radians.
