01 Key Concepts
What is a Point?
An exact position in space, usually labeled with a capital letter like A, B, or C, and represented by a dot.
Points Have No Dimension
A point has no length, width, or height — it's purely a location.
Collinear Points
Three or more points that all lie on the same straight line.
Coplanar Points
Points that all lie within the same flat plane.
Naming Points
Points are the foundation for naming every other geometric figure — lines, angles, and shapes are all defined using points.
02 Solved Examples
Example 1 Points A, B, and C lie on the same straight line. What term describes them?
- Points that lie on the same line are described by a specific geometric term.
Answer: They are collinear points
Example 2 Does a single point have any length or area?
- By definition, a point represents only a location, not a measurable size.
Answer: No, a point has zero length, width, and area
Example 3 If points D, E, F, and G all lie flat on the same tabletop, what term describes them?
- Points lying within the same flat surface (plane) share a specific term.
Answer: They are coplanar points
