The set square is, along with the T-square, one of the basic measuring tools and, certainly, one of the essential school materials in subjects such as technical drawing, art, or technology. This template, which may be graduated or not, and has the shape of an isosceles triangle, is used to draw perpendicular straight lines and to measure and obtain angles (among other things).
