The undefined term in geometry that has no dimension is "point".
What is a point?
A dot is used to symbolize a point, which is a place in any space (.). It is not any size, shape, length, or height. It is marked with capital letters and serves as the starting point for drawing any figure or form.
The types of points in geometry are explained below;
- Collinear Points and Non-Collinear Points: Collinear points are those that lie along a single straight line with three or more other points. Non-collinear points are a set of points that do not all lie along the same line.
- Coplanar Points and Non-Coplanar Points: A collection of points is said to have been coplanar if they all lie on same plane. Non-coplanar points are a group of points which do not share a plane.
Some key features of point are-
- There are no lengths, widths, shapes, or sizes for points.
- A line is formed when two separate points are joined.
- Two or more points that lie on a single straight line are collinear points.
- Coplanar points are 2 different or even more points that are located on the same plane.
