Revision I

Dear all,

Let us recap. Every day I will be posting up revision notes. Do read through. Practice makes perfect. Memorize these basic concepts and formulas.

1m = 100cm

1km = 1000m

1kg = 1000g

1 litre = 1000ml

- Perpendicular lines are formed when two straight lines meet at a right angle.
- We use a ruler to measure perpendicular lines.
- The two lines that meet must fit the edges of the ruler PERFECTLY!




Parallel lines are two straight lines that do not meet but are always equal distance apart from each other.
