This example demonstrates the geometric construction of an ellipse and its relationship with conic sections. Core math concepts include ellipse definition, conic intersection, and coordinate geometry. Construction highlights: using Point, Intersect, and Cone commands. Suitable for high school mathematics teaching and geometric construction learning.

GeoGebra Commands & Parameters

  1. Point(zAxis) → A
  2. Intersect(yAxis, xAxis) → B
  3. Cone(A, B, 2) → a, c, b
  4. Point(zAxis) → C
  5. Cone(C, B, 2) → d, e, f

AI Drawing Prompt Reference

In a 3D coordinate system, place two points along the vertical axis and one point at the origin on the horizontal plane. Using the first vertical point as the apex and the origin as the center of the base, draw a cone with base radius 2. Then, using the second vertical point as the apex and the same origin as the base center, draw another cone with the same radius. The two cones intersect along a closed spatial curve, which forms an ellipse. Show the two cones clearly, their common base center, and the intersecting ellipse, with coordinate axes indicated.
