2 Three-Dimensional Shapes

3 TThese shapes are solid or hollow. TThey have three dimensions – length, width and height.

4 PPart of a shape that is flat.(Or curved) EE.g. A cube has 6 of these.

5 TThe line where two faces meet. EE.g. A cube has 12 of these.

6 TThe place where three or more edges meet. TThis pyramid has 4 of these.

7 AA three- dimensional shape which has 6 square faces all the same size. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular

8  Face of a cube

11 AA three- dimensional shape which has 6 rectangular faces. Some faces parallel Some edges parallel Some faces perpendicular Some edges perpendicular

12  Faces of a rectangular prism

15 AA three dimensional shape with a circle at its base and a pointed vertex. No perpendicular faces or edges No parallel faces or edges

16  Face of a cone

19 AA three- dimensional shape with circular ends of equal size. Some faces parallel Some edges parallel Some faces perpendicular No edges perpendicular

20  Face of a cylinder

23 AA three-dimensional shape which has a polygon for its base and triangular faces which meet at one vertex. E.g. Triangular pyramid Square pyramid Hexagonal pyramid Pentagonal pyramid

24  Face of a pyramid

25 No faces perpendicular Some edges perpendicular No faces parallel Some edges parallel

28  A perfectly round three-dimensional shape, like a ball. It has only one curved face. No perpendicular faces or edges No parallel faces or edge s

37 Creating 3- Dimensional Shapes 1.Cut out the shape along the outer edge. 2.Fold all the edges of the shape first. 3.Use a small amount of glue on the shaded areas. 4.Carefully fold and press the shaded areas to the back of the faces.
