Alternate Segment Theorem Demonstration by teo lip seng
Loading the math board and drawing, please wait…
This example demonstrates the Alternate Segment Theorem, where the angle between a tangent and a chord is equal to the angle in the alternate segment. It involves core concepts like tangents, chords, circle properties, and angles. Constructed using GeoGebra commands such as Intersect, Point, Circle, Tangent, Polygon, LineBisector, Line, Angle, and Vector. Suitable for high school students learning about circles and trigonometry to understand and verify the theorem.
