When To Use

What doesplane mean?

In geometry, a plane  is a flat, two-dimensional surface with an infinite height and width. It’s one of the basic concepts of geometry.Think of a flat sheet of paper. A physical sheet of paper has three dimensions: length, width, and (a small) height. If that sheet of paper had zero height and its length and width extended forever, it would be a plane. Obviously, such a shape is theoretical—it’s used as a basis for geometric calculations.A plane is one of several basic concepts students need to begin to understand geometry. Another is a point. Unlike a plane, it has no dimensions, such as length or width. It is found by using coordinates. A third concept is a line. Like a plane, a line also extends forever but only in two directions.Understanding what a plane is matters because angles and two-dimensional shapes, such as squares, triangles, and circles, are represented as points, lines, and line segments on a plane. It also helps you understand three-dimensional space and three-dimensional objects, which have height as well as length and width. Plane has several other meanings, some of which have different roots. More generally, it can refer to any flat or level surface.
