More concepts to explore
Non-Euclidean geometry
Changing the parallel-postulate setting yields geometries with different angle and distance behavior.
Polyhedra
A polyhedron has polygonal faces meeting along edges and vertices.
Sets
A set is a collection of distinct objects; membership is different from inclusion.
Angles
An angle measures rotation between rays sharing an endpoint.
Area and volume
Area measures planar regions and volume measures spatial regions in corresponding squared or cubed units.
