What is the function of the T Square?

In respect to this, what are the types of T Square?

Most widely known are the T square, triangle, protractor, and compass; the parallel straightedge is an alternative to the T square. The drafting machine, introduced about 1930, allows a straightedge to be moved while maintaining any desired angle between it and the edge of the drawing board.

how will you test the set square and T square? Set squares are only accurate if they are used along with a T-square. The set square must rest on the T-square which should be pushed against the edge of the board. If the T-square is not right against the edge of the board (if there are even small gaps) lines drawn at an angle will not be accurate.
