Class 7 Maths Visualising Solid Shapes Introduction

Introduction: Plane Figures And Solid Shapes

Most of the objects that we see can be associated with basic shapes. A closed, two-dimensional or flat figure is called a plane shape. Plane figures made of lines are called polygons. Triangle and squares are examples of polygons. Example: We can say figures drawn on paper which have only length and breadth are called 2-d figures.

All these objects occupy some shape and have three dimensions- length, breadth and height or depth.
