CAN WE PLACE SET SQUARE ANYWHERE ON LINE AB?
Hi Anubhuti!
To draw a perpendicular to a line AB through a pint L on AB using set square and roller (as shown in second video), you need to place setsquare at L only.
To draw a perpendicular to a line AB through a pint C not on AB using set square and roller (as shown in fourth video), you need to place the setsquare anywhere on line AB.
Cheers!
