#### About NCERT Solutions for Class 7 Maths Chapter 15

In Class 7 Maths Chapter 15, the questions are based on basis of identification of parts of solid (dimensions) figures. We will learn the relations among Edges, Vertices and Faces of solid figures. We will draw the NETS (NETS are 2-D figures, which when folded results in 3-D figures0 for solid figure. Drawing solid figures on the flat surfaces using Oblique Sketches and Isometric Sketches.

1. Oblique Sketch: The sizes of the front faces and its opposite are same and The edges, which are all equal in a cube, appear so in the sketch, though the actual measures of edges are not taken so.

2. Isometric Sketch: An isometric sketch is drawn on an isometric dot paper, a sample of which is given at the end of this book. In an isometric sketch of the solid the measurements kept proportional.

Important to Remember:

1. Solid shapes can be drawn on a flat surface (like paper) realistically. We call this 2-D representation of a 3-D solid.

2. Visualizing solid shapes is a very useful skill. You should be able to see ‘hidden’ parts of the solid shape using dots.

3. The corners of a solid shape are called its vertices, the line segments of its skeleton are its edges and its flat surfaces are its faces.

### Important Questions on Class 7 Maths Chapter 15

(i) By cutting or slicing, the shape, which would result in the cross-section of the solid.

(ii) By observing a 2-D shadow of a 3-D shape.

(iii) By looking at the shape from different positions-the front-view, the side-view and the top-view.

(i) An oblique sketch which does not have proportional measurements.

(ii) An isometric sketch which is drawn on an isometric dot paper. In this sketch of the solid, the measurements are kept proportional.
