Visualizing solid shapes is an NCERT chapter that makes you familiar with the basics of shapes and geometrical applications of these shapes. You might have come across the solid shapes often around you. We can classify shapes based on the number of axes used to define their dimensions. If you have any object defined using length and breadth only, then it is the two-dimensional shape. If you need three parameters to define the solid shape, then it is a three-dimensional shape. We can use oblique sketches or isometric shapes to depict any three-dimensional shape on 2D paper. Let’s check some examples of geometric shapes of both these categories.
