Learn about the essential properties of plane shapes, polygons. Our easy to Example: For a pentagon (a five-sided shape) the calculation would be: 5 - 2 = 3. Each corner of a polygon where two sides intersect is called a vertex of the polygon. For example, a triangle is a polygon with 3 sides. There are also three. A polygon is a flat figure that is made up of straight lines and is enclosed. 3 sides - Triangle; 4 sides - Quadrilateral; 5 sides - Pentagon; 6 sides - Hexagon.

For polygons with 3 through 20 sides, simply add gon to the prefixes at the left ( although a trigon is more commonly called a triangle and a tetragon. Equilateral Triangle - An equilateral triangle is the only triangle that can be classed as a regular polygon because it 3 sides of equal length and 3 angles of equal.
