Geometric Terms and Properties

The Basic Building Blocks of Geometry

In geometry, the terms point, line and plane are considered undefined terms since they are explained using only examples and descriptions. Yet, these terms are useful in defining other geometric terms and properties.

Collinear points are points that lie in the same line.


Coplanar points are points that lie in the same plane.
