Warm-up Day 51: Right Triangle Fractal Construction with Rotation and Mirror Tra

This example demonstrates the recursive construction of fractal patterns based on right triangles using rotation, reflection, and intersection operations, exploring self-similarity in similar triangles. Core mathematical concepts include: right triangle properties, congruence and similarity transformations, rotational symmetry, and fractal geometry. Construction highlights: GeoGebra commands Rotate for generating angles α, β, γ, δ; Angle for labeling; Line and Intersect for building segments and intersection points; Polygon for drawing polygons (including kite shapes); Mirror for reflection symmetry; and Text for annotations. This example is suitable for middle to high school geometry courses and can serve as warm-up exercises or classroom demonstrations to help students visually understand geometric transformations and the aesthetic structure of fractals.
