What Is in Shapes Around Us? (Class 4 Maths Chapter 1)
- A prism has two matching flat ends joined by rectangles; a pyramid has one base and triangles that meet at a single top point.
- Faces are the flat surfaces, edges are the lines where two faces meet, and corners are the points where edges meet. For every solid with only flat faces (the prisms and pyramids), F + V – E = 2.
- A net is a solid opened out flat. Folding the net along its dotted lines gives the solid back.
- Two lines meeting at a point make an angle. An angle smaller than a right angle is acute; one bigger is obtuse.
- A triangle is rigid — pushing a side does not change it. A rectangle, a square and a pentagon all lean over when pushed.
- In a circle every point of the border is the same distance from the centre. The diameter is double the radius.
- A shape has as many angles as it has sides.
