SUMMARY
The equation that requires angular measures to be expressed in radians for validity is option C: ω² = ωø² + 2αθ. This conclusion is based on the necessity of using radians in angular motion equations to maintain dimensional consistency. The discussion emphasizes the importance of understanding the symbols in the equations, such as α (angular acceleration), ω (angular velocity), and θ (angular displacement), to interpret their validity correctly.
