## AP State Board Syllabus 7th Class Maths Notes Chapter 14 Understanding 3D and 2D Shapes

→ A net is a sort of skeleton – outline in 2-D, which, when folded, results in a 3-D shape. Each shape can also have more than one net according to the way we cut it.

Eg:

→ 3-D shapes can be visualised by drawing their nets on 2-D surfaces.

→ Oblique sketches are drawn on a grid paper to visualise 3-D shapes.

→ Isometric sketches can be drawn on a dot isometric paper to visualise 3-D shapes.
