This website is best for students to learn online and clear there outed, we have to learn about different shapes with 3-D view form Top side or lateral sides. This also provides the information about how to find number of faces, vertices and edges of a solid figure. Each of these solids is made up of polygonal regions which are called its faces; these faces meet at edges which are line segments; and the edges meet at vertices which are points. Such solids are called polyhedrons. A pyramid is a polyhedron whose base is a polygon and whose lateral faces are triangles with a common vertex. (If we join all the corners of a polygon to a point not in its plane, you get a model for pyramid).
