A point is a position in space which has no size, but which does have position.

In geometry, a point has no size, but has a position. This means it has no volume, area or length. We usually visualize a point by a small cross 'X' or by a small dot (a small, round shape). Points are always labelled by capital letters (A, B, C...X, Y, Z).^[1][2] It is one of the most fundamental but undefined terms in geometry.^[3]

In general, two points can be:

• Coincident (they are one and the same)^[source?]
• Not coincident (they are not one and the same)

and are always:

• Coplanar (on the same plane)
• Colinear (on the same line)
• Concyclic (on the same circle)

Three points can be:

• Colinear
• Coincident
• Not coincident
• Not colinear

and are always:

• Coplanar
• Concyclic

Four points can be:

• Coplanar
• Colinear
• Coincident
• Not coincident
• Not colinear
• Not coplanar

• Line
• Plane
