Do not worry about your problems in Mathematics. I can assure you mine are still greater. – Albert Einstein
At whatever age you might have you might bought your first geometry box, from that day to till, without a doubt we have almost never used the three pieces- Set square and Divider.
Now first of all we are talent and make some use of what so ever we get, in my student life I use to bind supplementary copies with divider and use set squares as scale when the scale go missing. But, instead of our exceptional uses where are these instruments used in mathematics or engineering or so…
Set Square fulfill following purposes,
Drawing the standard angles and triangles
Drawing two parallel line at givenDrawing perpendicular lines to a given line
For being real when you come to engineering or do some exciting experiments in physics or majorly civil engineering you will come across surfaces where your scale would not give you required result, the picture below will depict everything.This is the reason why the divider is much tight that the compass that we use
