Wikimedia Commons has media related to Geometry.
Geometry is the branch of mathematics dealing with spatial relationships. The word Geometry means to measure the earth. From experience, or possibly intuitively, people characterize space by certain fundamental qualities, which are termed axioms in geometry. Such axioms are insusceptible to proof, but can be used in conjunction with mathematical definitions for points, straight lines, curves, surfaces, and solids to draw logical conclusions.
