Closed Figure

Polygons

Definition

A closed figure is a geometric shape that starts and ends at the same point, forming a complete boundary with no openings.

Description

In geometry, the concept of a closed figure is fundamental as it pertains to shapes that enclose a space. These figures are essential in the study of polygons, which are closed figures with straight sides. Examples of closed figures include triangles, rectangles, and circles. Understanding closed figures is crucial for various applications in mathematics, including calculating area, perimeter, and understanding more complex geometric properties. Closed figures also have significance in real-world contexts such as architecture, engineering, and computer graphics, where defining and manipulating enclosed spaces is often necessary. The properties of closed figures, such as symmetry and angles, play a vital role in these fields, making them a key topic in both theoretical and applied geometry.
