Pyramids and Prisms Characteristics

The video tutorial explains the differences between prisms and pyramids. It provides examples of each shape and describes their characteristics. A prism is a three-dimensional shape with two identical, parallel bases and flat faces that are parallelograms or rectangles. A pyramid has a single polygonal base and triangular sides that meet at an apex. The video concludes with examples of shapes that are neither prisms nor pyramids.

What is the main difference between a prism and a pyramid?

• A prism has curved surfaces, while a pyramid has flat surfaces.

• A prism has two identical bases, while a pyramid has one base.

• A prism is always triangular, while a pyramid is always rectangular.

• A prism has a single base, while a pyramid has two.
