Similar Transformation and Polygon Demo

This example demonstrates the similarity transformation (Dilation) of polygons in the coordinate plane, showing the scaling effect through a center and scale factor; core math concepts include similar triangles, angle transformation, coordinate geometry, and ratio relationships; construction highlights use Polygon command for creating polygons, Angle command for defining angles, and objects like A, B, C for vertices, c, a, b for related elements, α, β, γ for angles; suitable for high school mathematics teaching to understand transformation geometry and polygon properties.
