Angle Addition Postulate Demo

This example demonstrates the Angle Addition Postulate, showing how the sum of two angles equals the measure of the resulting angle when combined. Key math concepts include angle measurement, rays, and geometric construction. It uses GeoGebra commands like Ray, Angle, and defines points A, B, f, C, g, D, h, and angles α, β, γ, with text annotations text1, text2. Suitable for high school mathematics education to visually illustrate the postulate and its applications.
