You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.
A shape with three sides is called a triangle. A shape with ten sides is called a decagon.
