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.
