This animation introduces the basic classification of angles: acute, right, obtuse, straight, and reflex. A rotating ray sweeps from zero degrees, pausing at each category to highlight the degree range and a real-world example, such as a clock hand or an open door. Visual markers and color coding help distinguish each type clearly. Designed for introductory geometry classes, it gives students a simple, visual reference for recognizing and naming angles by their measure.
