{"type":"rich","version":"1.0","title":"Unit Circle Identities","description":"Players match unit-circle angle relationships such as θ and -θ or θ and 2π + θ with the correct trigonometric equation, like sin(-θ) = -sin(θ) or cos(θ + 2π) = cos(θ). The goal is to connect symmetry and periodicity patterns on the unit circle to trig function values.
