Angle Measurements
Central Angle: 0°
Inscribed Angle: 0°
This interactive tool demonstrates the Circle Theorem involving central angles and inscribed angles. As you move points along the circle, the app dynamically shows how the central angle is always twice the inscribed angle subtended by the same arc. This visual approach helps students, teachers, and anyone learning geometry understand the relationship between these two angles more intuitively.
An inscribed angle is always half the central angle when they subtend the same arc.
Inscribed Angle = ½ × Central Angle
