Junior Cert Section A
Equal Widths
This question is based on Basic Construction 2-11 (p14 in Textbook). If you have a line of unknown or awkward length (125.32mm):
There are two ways to divide up the line (step 2):
- draw another line that you can easily divide into the amount of sections you need at an angle to the original line
- divide it up
- connect the end of the last division to the end of the original line
- draw lines parallel to the line in step 3 from each point
- the points where these lines meet the original line give you your divisions
There are two ways to divide up the line (step 2):
- use your compass to mark off equal divisions
- make the line a length that is easily divisible, ie, for 7 divisions use a 140mm line
Very Important - You MUST you the construction method above, measuring the length and dividing it isn't accurate and will get you 0 marks.
