This example demonstrates drawing points and shapes on the surface of a sphere. It involves core mathematical concepts such as sphere, intersection, derivative, circumcircle, and rational numbers. The construction uses GeoGebra commands like Intersect, Point, Sphere, Circle, and Polygon. Suitable for high school and above, ideal for teaching and exploring solid geometry and analytical geometry.

GeoGebra Commands & Parameters

  1. Intersect(zAxis, xAxis) → A
  2. Point(zAxis) → B
  3. Sphere(A, B) → a
  4. Intersect(xAxis, yAxis) → E
  5. Point(yAxis) → F
  6. Circle(E, F) → c
  7. Polygon(G, H, I) → poly1, i, g, h
  8. Polygon(J, K, L, M) → poly2, j, k, l, m
  9. Point(yAxis) → O
  10. Circle(E, O) → d
  11. Circle(P, Q) → e
