• A Flat Surface that extends into Infinity in all directions is known as a Plane.

More about Plane

• It is also called as two-dimensional surface.
• Any three noncollinear points lie on one and only one plane.
• A Plane has Infinite width and length, zero thickness, and zero curvature.

Example of Plane

• The figure shown is a Flat Surface extended in all the directions. So, it is a plane.
