Polygon
a closed figure with at least 3 sides, where all sides are straight (no curves)
A polygon is a closed shape that has three or more straight sides and angles. Polygons are two-dimensional figures and can have any number of sides, however, they must have a minimum of three. Some examples of polygons include triangles, rectangles, squares, pentagons, hexagons, and octagons.
The interior angles of a polygon add up to a specific sum, which varies depending on the number of sides it has. For example, the sum of interior angles of a triangle is always 180 degrees, whereas the sum of interior angles of a hexagon is always 720 degrees.
Polygons can be classified as either regular or irregular. A regular polygon has all sides and angles that are equal in size, while an irregular polygon has sides and angles that vary in size.
The perimeter of a polygon is the total distance around the outside of the shape and is equal to the sum of the lengths of all its sides.
In real-life, polygons are commonly used in architecture, engineering, and design. For example, polygons are used to design bridges, buildings, and roads. In addition, computer graphics and video games use polygons to create three-dimensional shapes and characters.
