RD Sharma Solutions Class 8 Visualising Shapes

RD Sharma Solutions Class 8 Chapter 19

In earlier classes, we have learned that figures having the length only are known as one-dimensional figures. Figures having length and breadth are the two-dimensional figures. It is very convenient to visualize 2D figures which are drawn on the plane of the paper as they have length and breadth only. If a 3D shape is represented by a figure drawn on the plane of the paper, that is when the length, breadth, and height of a 3D shape is represented by lines drawn on the plain paper which is a two-dimensional figure, then it is slightly difficult to visualize the shape.

Learn about different concepts related to solid shapes and its related terms such as a face, edges, vertices, lateral surface and base of different types of polyhedrons. Understand the difference between the regular polyhedron and convex polyhedron. Learn about prism and pyramid and terms related to it.

Easily visualize 3D shapes through the use of nets. A net for a 3D shape is a sort of skeleton-outline in two dimensions which, when folded, results in the three-dimensional shape.Learn these concepts easily by practicing the questions from the exercises given in RD Sharma solution for the chapter “Visualising Shapes”.
