This example demonstrates the construction of a pentagonal pyramid. It involves polygon, similarity transformation, and solid geometry. Using commands like Polygon, Pyramid, and Net in GeoGebra, the base and sides of the pentagonal pyramid can be constructed. Suitable for middle and high school students learning solid geometry.

GeoGebra Commands & Parameters

  1. Polygon(A, B, 5) → poly1, a, b, c, d, e, C, D, E
  2. Pyramid(poly1, 6) → f, F, edgeDF, edgeEF, faceABF, faceBCF, faceCDF, faceDEF, faceAEF, edgeAF, edgeBF, edgeCF
