What is a polygon?
Equiangular polygon polygon with angles that are the same EXAMPLES: equilateral triangle, ANY square or rectangle Equilateral polygon all sides the same EXAMPLES: equilateral triangle, ANY square Regular polygon polygons that are equiangular and equilateral EXAMPLES:sqaure, pentagon, hexagon, equilateral triangle (triangle that has 60 degree angles and equal sides) Equilateral and equiangular are sometimes the same, like in squares. However, an equilateral parallelogram is not always the same as an equiangular one.
The word polygon is a combination of two Greek words: “poly” means many and “gon” means angle. Along with its angles, a polygon also has sides and vertices. “Tri” means “three,” so the simplest polygon is called the triangle, because it has three angles. It also has three sides and three vertices. A triangle is always coplanar, which is not true of many of the other polygons. Basically, polygons are many-sided figures, with sides that are line segments. They are named according to the number of sides and angles they have. The most common polygons are the triangle, rectangle and the square. A regular polygon is one that has equal sides, like a square, equilateral triangle etc. Polygons also have diagonals, which are segments that join two vertices and are not sides The table lists all the polygons having up to 10 sides. (it is extracted from www.math.com) Types of Polygon Regular – all angles are equal and all sides are the same length. Regular polygons are both equiangular and equilate
