VectorSolid GeometryGeometric Construction
This example demonstrates the cross sections of a sphere, cone, and cylinder. By constructing orthogonal lines, circles, vectors, and more, it provides a visual understanding of the geometric properties of the cross sections. Suitable for students at junior high school level and above learning solid geometry.
