Reflection Planes of a Regular Tetrahedron

2020-10-27 01:53
This GeoGebra applet demonstrates the reflection planes of a regular tetrahedron. By constructing vertices, edges, faces, and edge midpoints, it dynamically visualizes spatial symmetry. It helps students intuitively understand reflection symmetry in 3D solid geometry and explore the geometric properties of regular polyhedra, suitable for high school education.
