Reflection Transformation by Paul Jorgens
Loading the math board and drawing, please wait…
This example demonstrates the reflection transformation of points, triangles, and polygons, involving core concepts like symmetry, reflection, and coordinate geometry. It uses commands Polygon and Mirror, with objects A, B, C, and poly1. Suitable for middle school and above learning geometric transformations and coordinate geometry.
