A triangular ruler, also known as a set square, is a tool used in drafting and drawing to create precise angles and straight lines. Typically made of plastic or wood, it features a triangular shape with two right angles and one acute angle, allowing for various angular measurements. It is commonly used in technical drawing, geometry, and carpentry to assist in creating accurate geometric shapes and layouts.
