Triangular Pyramid by HCY Maths

This example demonstrates the 3D geometric structure of a triangular pyramid. Key math concepts include solid geometry, the formation of polygonal faces and edges. Construction highlights involve using the Pyramid command, defining vertices A, B, C, D, base size 'a', labeling faces (faceABC, faceABD, faceBCD, faceACD), and edges (edgeAB, edgeBC, edgeAC, edgeAD, edgeBD, edgeCD). Suitable for high school geometry teaching or construction practice.
