A pyramid is a polyhedron with three or more faces. It is formed by joining the points of a finite number of vertices together. The base of a pyramid is the largest face, and each subsequent face is smaller than the base.
A cone is a polyhedron with two bases and a circular top. It is formed by joining the points of a finite number of vertices together, and it has a circular base and a pointed top.
Development:
The development is the process of constructing a surface from a collection of points. There are two main methods for developing pyramids and cones:
1. Using nets:
A net is a planar figure that can be folded to create a 3D shape. To develop a pyramid or cone using a net, we start by folding the net along the lines of its creases. We then connect the vertices to form the surface of the shape.
2. Using construction:
Construction is a method of constructing a shape by starting with a set of basic shapes and combining them to form the desired shape. To develop a pyramid or cone using construction, we start with a set of cones and pyramids and combine them to form the surface of the shape.
Examples:
A pyramid is developed from a net by folding the edges of the net along the lines of its creases.
A cone is developed from a set of cones by joining their bases together and then drawing a line from the base to the tip
