They cannot be picked up. A polygon is a 2D shape with straight sides that meet at vertices. Polygons have names that show the number of sides they have. A three-dimensional (3D) shape is a solid ...

We’re at the Polygons annual party. It’s polygons only so to get a ticket, you have to be a 2D shape, with straight sides. Polygons can be grouped based the number of sides they have.

Polygons can look quite different, but have the same name. For example, look at these two shapes and count the sides on each. Can you see both shapes have 6 sides, so both shapes are hexagons.
