T-SQUARE

T-square noun
A T-shaped instrument for drawing or testing right angles.
Etymology:  Its name comes from its resemblance to the letter T.

When I was in High School, we had a few art lessons in "technical drawing" where we learnt how to use various drawing instruments, such as T-squares, set squares, protractors, compasses, etc, in order to construct precise drawings of various objects. These drawings could then be used as a guide for constructing these objects in wood, metal or plastic.

It is rare to find such instruments nowadays as technical drawings can be done quite easily by the use of various drawing programs on a computer...
