# NCERT Solutions Class 7 Maths Chapter 15 Visualising Solid Shapes

Geometry is the study of shapes and objects in our environment, both two-dimensionally and three-dimensionally, as they all possess length, breadth, and height. The NCERT Solutions for Class 7 maths Chapter 15 Visualising Solid Shapes starts with the explanation of terms like 2D and 3D and why they are called by their relevant names. The terms like vertices, edges, and faces are explained with the help of diagrams.

The students need to know the difference between plane geometry and solid geometry. Plane geometry, also known as two-dimensional geometry, is the study of lines and shapes such as squares, triangles, rectangles, and hexagons, whereas solid geometry is the study of prisms, cylinders, cubes, pyramids, spheres, and other three-dimensional objects.

There are certain activities in the NCERT solutions Class 7 maths Chapter 15 which will help students understand the three-dimensional space and how objects can be constructed in 3D. For this, they are explained to make frames or nets of respective shapes and asked to try to build those shapes with the prepared cutouts or frames. This will help in building the visualization skills necessary for the exercise questions. The pdf file of the Class 7 maths NCERT solutions Chapter 15 Visualising Solid Shapes given below and also find some of these in the exercises given below.

## List of Formulas in NCERT Solutions Class 7 Maths Chapter 15

The NCERT solutions Class 7 maths Chapter 15 covers the basics of geometry as it teaches important skills that are very much required while solving problems in geometry. This chapter doesn't deal with any formulas, but there are certain definitions and facts which the students should know in order to solve the problems. Some important facts covered in NCERT Solutions for Class 7 maths Chapter 15 are given below :

**Plane and Solid Shapes:**The plane shapes would include shapes which have only length and breadth, such as square, rectangle, hexagon, etc., while the solid shapes have height too along with the length and the breadth, examples being, cuboid, cube, sphere, cone, etc.

**2D depiction of a 3D solid:**This can be achieved when the image of the solid is drawn on paper, and there are two techniques to do this. One is an oblique sketch, and the other is an isometric sketch.
