This example demonstrates a triangular pyramid and its net, using GeoGebra's Pyramid command to construct the solid and the Net command to draw its unfolded form. The core mathematical concepts include solid geometry of polyhedra, the relationships between faces and edges, and the principles of folding and unfolding planar nets. The construction highlights the use of Point to create vertices, Polygon for the triangular base, Pyramid to generate the tetrahedron, and Net to produce the flat layout, with objects labeling each face and edge. It is suitable for high school geometry classes, 3D visualization exercises, and engineering drawing applications involving nets.
