A prism is a 3D shape with a constant polygon shaped cross-section. A prism is named by the shape of its polygon cross-section. When the cross-section is a triangle, the prism is called a ...

Two-dimensional (2D) shapes are completely flat. They have two dimensions – length and width. A polygon is a closed 2D shape with straight sides that meet at vertices. Polygons can be regular or ...

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.

Two-dimensional (2D) shapes are completely flat. 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 ...

There are many types of nets for the different 3D shapes. A net is made from polygons that can be folded and joined to make a polyhedron. Here is the net of a triangular prism. Why not see how ...
