Right angled ruler / Right angled ruler

Right angled ruler

We often need to draw right angle line, whether it is in the cut or drawing. If we had a square , that would be more accurate, but the square is very inconvenient to carry .Adding the cut marks on the normal ruler ,and it will be a square!
