triangles have three every thing three sides ,corners ,angles..pentagons are relly cool they have five sides andfive lines of symmitry. A sure way to tell if a four sided figure is a square is that a square allways has all the sides equal. octogons have eight corners and eight sides.
hexagons havesix corners and six sides. hexagons aren't exatly like triangles even though there made of six triangles they have twice as many sides and corners than a triangle.

You know your geometry quite well! Can you spot what's wrong in this picture? -Mrs. Maley
