A polygon is a shape with 3 or more sides

Poly means how many and gon means angles in the language of Greece

Triangle3 sided 2D shape

There are 6 different types of triangles the equilateral triangle, the scalene triangle, the isosolese triangle, the right triangle, the obtuse triangle and the acute triangle

The equilateral triangle is the only triangle with equal sides

All angles are acute

3 vertices

Square

4 sided 2D shape

All the sides are the same length

All angles are right

4 vertices
