This example demonstrates the geometric relationships and transformations between a sphere, planes, and points. It involves core concepts like solid geometry, rotation, symmetry, and intersection calculations. Construction highlights include commands like Intersect, Sphere, PointIn, Segment, Mirror, Plane, and IntersectPath, along with objects like radius and points. Suitable for high school students and math enthusiasts studying spatial geometry and transformations.

GeoGebra Commands & Parameters

  1. Intersect(zAxis, yAxis) → A
  2. Sphere(A, radius) → b
  3. PointIn(b) → B
  4. Segment(B, A) → c
  5. Mirror(B, A) → B'
  6. Intersect(yAxis, b, 2) → C
  7. Plane(B', C, B) → d
  8. IntersectPath(d, b) → e

AI Drawing Prompt Reference

Draw a sphere with its center at the intersection of the z-axis and y-axis, and a radius of 1. Then pick a point B on the sphere and connect it to the center A. Mirror point B over A to get B'. Find the intersection of the y-axis and the sphere to get point C. Use B', C, and B to create a plane d, and then find the intersection line e between plane d and sphere b.
