This example demonstrates how to dynamically adjust the cross-sections of a pyramid to observe its geometric shape changes. Key math concepts include volume calculation, sequences and series, inequalities, linear equations, division, and trigonometric functions. It uses GeoGebra commands/objects like Line, Point, Polygon, Pyramid, Plane, and IntersectPath. Suitable for high school students studying solid geometry, calculus, and function graphing.

GeoGebra Commands & Parameters

  1. Line((0, 0), (0, 1)) → g2
  2. Point(f) → A
  3. Polygon((4, 1, 1), (4, 1, -1), (4, -1, -1), (4, -1, 1)) → base, a, b, c, d
  4. Pyramid(base, (0, 0, 0)) → pyra, face1, face3, face4, face2, edge1, edge2, edge3, edge4
  5. Plane((x(A), y(A), y(A)), (x(A), (-y(A)), y(A)), (x(A), (-y(A)), (-y(A)))) → slicePlane
  6. IntersectPath(slicePlane, pyra) → poly1, poly2, e, g, h, i, j, k, l, m, B, C, D, E, F, G, H, I
