Sphere Geometry: Properties and Projections

Explores the properties and sections of a sphere, including symmetry, tangent planes, and circle projections.

Explores affinity in geometry, segment construction, ellipses, and circle projections.

Explores true angle magnitude, reflections, isometries, and symmetries in modern geometry, with practical CAD applications.

Covers the missing projection of points on a sphere using principal planes.

Explores ellipse construction using the Dandelin theorem and properties of conics in space.
