This example demonstrates the net of a pyramid. Key mathematical concepts include solid geometry and geometric construction. Using GeoGebra commands such as Point, Polygon, Rotate, etc., the faces of the pyramid can be constructed and unfolded. Suitable for middle and high school students learning solid geometry.

GeoGebra Commands & Parameters

  1. Point(zAxis) → V
  2. Polygon(A, B, C, D) → q1, a, b, c, d
  3. Polygon(C, B, V_2) → t1, f, c_1, b_1
  4. Rotate(A_1, (t / e * π / 2), c_1) → A_2
  5. Rotate(D_1, (t / e * π / 2), b_1) → D_2
  6. Polygon(V_2, B, A_2) → t2, a_2, v_2, b_2
  7. Angle(g, h) → α
  8. Polygon(C, D_2, V_2) → t3, v_1, c_2, d_2
  9. Rotate(B, i, b_2) → E
  10. Polygon(V_2, A_2, E) → t4, e_1, v_3, a_1
