- SYMMETRY INTOTWO DIMENTION
Line of symmetry – lines that divides a figure into two equal parts.
e.g. How many lines of symmetry does
If you cut an arrange in two so that the two halves are identical, the cut is a plane of symmetry. e.g. (i) make a list of objects which have planes of symmetry
- sphere – cone
- cuboid – block
- Draw and state how many planes of symmetry a block has.
- planes of symmetry.
- How many planes of symmetry has
- a) a sphere
- b) a circular cylinder
infinite planes symmetry.
- Draw and state how many planes of symmetry a cuboid has

APPLIED A ARITHMETRIC
In this chapter, we are going to look at
- Decimal places
- Significant figures
e.g. i) correct the following number to the nearest integer
