Angles in polygons
This example demonstrates the relationship between the number of sides and the sum of interior angles in polygons. Key math concepts include polygons, interior angles, and mathematical induction. It is constructed using GeoGebra commands like Point, Polygon, and Angle, with a slider to adjust the number of sides dynamically. Suitable for middle school and above students to understand the sum of interior angles theorem and explore geometric relationships.
