List of basic geometry topics

For a more comprehensive list, see the list of geometry topics.

Geometry is one of the main branches of mathematics and deals with space and spatial relationships. It covers the measurement, properties, and relationships of points, lines, angles, curves, planes, and shapes, in both two- and three-dimensions.

The following outline is provided as an overview of and introduction to geometry:
