What are geometric plane shapes?What characteristics do they have? These are the questions that we will answer in this post. The principal geometric plane shapes are:. The Circle. The circle is a shape that can be made by tracing a curve that is always the same distance from a point that we call the center. The distance around a circle is called the circumference of the circle.

The topological plane has a concept of a linear path, but no concept of a straight line. The topological plane, or its equivalent the open disc, is the basic topological neighborhood used to construct surfaces (or 2-manifolds) classified in low-dimensional topology. Isomorphisms of the topological plane are all continuous bijections.

The Plane. In plane geometry, all the shapes exist in a flat plane. A plane can be thought of an a flat sheet with no thickness, and which goes on for ever in both directions. It is absolutely flat and infinitely large, which makes it hard to draw. In the figure above, the yellow area is meant to represent a plane.
