Opposite Angles of a Cyclic Quadrilateral
2024-12-27 02:30
This GeoGebra applet dynamically demonstrates the supplementary opposite angles theorem for cyclic quadrilaterals. Four points A, B, C, D are placed on a circle to form an inscribed quadrilateral. Using the Angle and Segment commands, interior angles α, β, γ, δ are measured in real time, verifying that each pair of opposite angles always sums to 180°. Dragging any vertex updates the angles interac
