A polygon is a closed figure consisting of line segments that are joined together. The name “polygon” comes from the Greek word for “many” (poly) and “angle” (gon). The segments that make up a polygon are called its sides or edges, and the points where the sides meet are called its vertices or corners.
The sides of a polygon can be all different lengths and the angles between them can also be different. However, if all the sides of a polygon are the same length and all the angles between them are the same, then the polygon is said to be regular.
There are many different types of polygons, but some of the most common are triangles, quadrilaterals, pentagons, hexagons, and octagons.
Triangles are the simplest type of polygon and they have three sides. The most common type of triangle is the equilateral triangle, which has three sides of equal length and three angles that are all 60 degrees.
Quadrilaterals are polygons with four sides. The most common type of quadrilateral is the rectangle, which has four right angles.
Pentagons are polygons with five sides. The most common type of pentagon is the regular pentagon, which has five sides of equal length and five angles that are all 108 degrees.
Hexagons are polygons with six sides. The most common type of hexagon is the regular hexagon, which has six sides of equal length and six angles that are all 120 degrees.
Octagons are polygons with eight sides. The most common type of octagon is the regular octagon, which has eight sides of equal length and eight angles that are all 135 degrees.
