Coordinate GeometrySolid GeometryGeometric Construction
This example demonstrates the cross sections created by slicing a plane through pyramids of different bases. Key mathematical concepts include the properties of cross sections in solid geometry. It uses commands such as Intersect, Sphere, Circle, Segment, PointIn, Plane, and IntersectPath in GeoGebra. Suitable for high school geometry lessons.

GeoGebra Commands & Parameters

  1. Intersect(yAxis, zAxis) → C_1
  2. Sphere(C_1, 2) → a
  3. Circle(C_1, 2, zAxis) → d
  4. Circle(C_1, 2, xAxis) → e
  5. Intersect(zAxis, e) → A_1, B_1
  6. Intersect(yAxis, d) → C_2, D
  7. Segment(C_1, D) → f
  8. Segment(C_1, A_1) → g
  9. PointIn(a) → A
  10. PointIn(a) → B
  11. PointIn(a) → C
  12. Plane(A, B, C) → h
  13. IntersectPath(h, a) → k
  14. IntersectPath(h, a) → p

AI Drawing Prompt Reference

Draw a sphere with a radius of 2 centered at the intersection of the z-axis and y-axis. Then draw two circles with a radius of 2 on the x-axis and z-axis, which intersect the sphere to form two circles. Find the intersection points A1 and B1 on the z-axis and C2 and D on the y-axis. Connect the center of the sphere to A1, B1, C2, and D to form line segments f and g. Select three points A, B, and C on the sphere to define a plane h, which intersects the sphere to form two intersection lines k and p.
