Points Cheat Sheet
In one line: a point is the most basic building block of geometry — an exact location in space with no size, width, or length of its own.
Key Ideas
1What is a Point?. An exact position in space, usually labeled with a capital letter like A, B, or C, and represented by a dot.
2Points Have No Dimension. A point has no length, width, or height — it's purely a location.
3Collinear Points. Three or more points that all lie on the same straight line.
4Coplanar Points. Points that all lie within the same flat plane.
5Naming Points. Points are the foundation for naming every other geometric figure — lines, angles, and shapes are all defined using points.
Worked Examples
Points A, B, and C lie on the same straight line. What term describes them?
They are collinear points
Does a single point have any length or area?
No, a point has zero length, width, and area
If points D, E, F, and G all lie flat on the same tabletop, what term describes them?
They are coplanar points
