Angles in Polygons by Katelynn Hanna

This example demonstrates the calculation and verification of the sum of interior angles in polygons. It involves core mathematical concepts such as the polygon interior angle sum theorem, angle measurement, and geometric construction. Key GeoGebra commands used include Segment, Angle, and Polygon, with labeled points A, B, C, and angles α, β, γ, δ. Suitable for middle school and above mathematics education to visually understand polygon angle properties.
