Regular Pyramid: Dynamic 3D Construction of Faces and Edges

This GeoGebra example demonstrates a regular pyramid as a dynamic three-dimensional geometry model, visualizing the spatial relationships among the base polygon, apex, lateral faces, and edges. Core mathematical concepts include regular polygons, pyramids, faces and edges, points-lines-planes in solid geometry, and parametric control via variables n (number of sides), r (base radius), and h (height). Construction highlights: Polygon creates the base regular polygon, Pyramid generates the solid, and Point, Segment, Ray, and Angle label vertices, edges, and angles. Sequence commands combined with list1 and list2 batch-generate faces (face1…face10) and edges (edge1…edge10); supporting objects include b, n, r, h, F, B₁, g, poly1, T, a, C, A, B, AB, FA, α, and TA. Suitable for high school solid geometry instruction and university analytic geometry demonstrations, ideal for teaching pyramid structure or independent student exploration of regular pyramid properties.
