The set square, also known as a triangle ruler, has been used for centuries in various forms. It is difficult to pinpoint a single inventor, as the concept of using a right-angled triangle for measuring and drawing dates back to ancient civilizations such as the Egyptians and Greeks. The modern version of the set square we use today likely evolved over time through contributions from mathematicians, architects, and engineers.
