What is prism and pyramid?

Pyramids. Prisms. Basic definition. A pyramid is

a three dimensional polyhedron shaped structure with

only one polygonal base and has triangular sides. A prism is a three dimensional polyhedron characterized by two bases which are polygonal in shape and rectangular sides perpendicular to the base.

What is a prism ks1?

A prism is a

type of three-dimensional (3D) shape with flat sides

. It has two ends that are the same shape and size (and look like a 2D shape). It has the same cross-section all along the shape from end to end; that means if you cut through it you would see the same 2D shape as on either end.

How do you describe a pyramid shape?

Pyramid Shape

A pyramid is a three-dimensional shape. A pyramid

has a polygonal base and flat triangular faces

, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex, and forms the triangular face, called the lateral face.
