perpendicular and inclined to HP and / or VP.)
Prisms:
A prism has certain properties:
 A prism is a type of solid (3D object) that has a polygon as a base.
 The top face of a prism is exactly the same as the base of the prism.
 The top face of a prism is parallel to the base of the prism.
 The side faces of a prism are rectangles that are perpendicular to the base.
Pyramids:
A pyramid is an object that has a polygon as its base and sides that converge (meet each other)
at one single point. The sides are not perpendicular to the base.
The properties of a pyramid are:
 Total Faces are all sides and a base (A square-based pyramid has five faces.)
 The faces of a pyramid meet each other at an edge.
 The edges of a pyramid meet each other at a vertex.
 The edges of the triangles that form the side faces converge at a vertex called the apex.

Cones
A cone is another example of a 3D object that has an apex.
The properties of a cone are:
 A cone has two faces. One of the faces is flat and the other face is curved.
 The base of a cone is a flat circle.
 A cone has only one side face, and this face is curved.
 A cone has only one edge. The edge of a cone is not a straight line - it is a curve.
 The edge of a cone is the circumference of the circle that forms the base of the cone.
 A cone has only one vertex.
Cylinders
In a cylinder, both the top and bottom faces are circles. The top and bottom faces are joined by a
curved surface that is perpendicular to the base.
The properties of a cylinder are:
 A cylinder has two flat faces and one curved face:
 The top face of a cylinder is also a circle. The two circles are equal.
 a cylinder has three faces: two flat circles and one curved surface.
 The faces of a cylinder meet each other at two edges.
