Plane in Geometry
In geometry, a plane is a flat, two-dimensional surface that extends infinitely in all directions. It has zero thickness, zero curvature, infinite width, and infinite length. Some common examples of plane figures include lines, rectangles, circles, and triangles. Planes can be formed by a line, a point, or a three-dimensional space, and they can appear as subspaces of higher-dimensional spaces. In Euclidean geometry, plane geometry deals with flat shapes that can be drawn on a piece of paper, and it is essential for measuring lines, angles, and surfaces, laying the foundation for learning solid geometry.
A plane is a fundamental concept in geometry, and understanding its properties and characteristics is crucial for various mathematical and practical applications.
