PolygonAngleGeometric Construction
This example demonstrates the properties of interior angles of polygons. Key mathematical concepts include polygons and angles. Using GeoGebra commands like Polygon and Sides, it dynamically shows the sum of interior angles of polygons. Suitable for middle school and above students to learn about the properties of polygon interior angles.
