# NCERT Maths Class 7 Chapter 15 Visualising Solid Shapes Exercise 15.1 Problems

The circle, square, rectangle, quadrilateral and triangle are some of the examples of plane figures. The cube, cuboid, sphere, cylinder, cone are some of the examples of solid shapes. Solid figures are of three dimensions known as(3-D) figures, plane figures are of two dimensions known as (2-D) figures.

• Nets for building 3-D shapes: A net is a skeleton outline of a solid that can be used for flooding.
• Drawing solids on a flat surface: We can call 2-D representation of a 3-D solid. Solid shapes can be drawn on flat surfaces.
• Oblique sketches: An oblique sketch doesn’t have propential lengths.
• Isometric sketches: On isometric dot paper an isometric sketch is drawn.
• Visualizing solid objects: The ability to see ‘hidden’ parts of the solid shape is required.

Now we are going to discuss a few solid shapes related to this chapter. #### Conclusion:

These are some of the solid shapes chapter topic problems which are very easy just once if we learn it will be very easy to learn and even to understand. It’s very important to learn. Everyone should learn this. It’s a very easy chapter when compared to all other chapters.
