This example demonstrates the formation of a cone by rotating a right triangle. Core mathematical concepts include solid geometry, rotational solids, and geometric transformations. The construction uses GeoGebra commands like Point, Intersect, Polygon, and Rotate to build the triangle and rotate it to form the cone. Suitable for middle school and above students to understand rotational geometry and spatial reasoning.

GeoGebra Commands & Parameters

  1. Point(zAxis) → A
  2. Intersect(xAxis, zAxis) → B
  3. Point(xAxis) → C
  4. Polygon(A, B, C) → poly1, c, a, b
  5. Rotate(poly1, α, zAxis) → poly1'
