A T-square is a technical drawing instrument used primarily for drawing straight lines and ensuring accurate right angles. It consists of a long, straight edge (the blade) attached to a shorter, perpendicular piece (the head or stock), forming a shape similar to the letter "T." The head of the T-square rests against the edge of a drawing board or drafting table, allowing the blade to provide a stable guide for drawing horizontal lines.  T-squares are versatile tools essential for anyone involved in technical drawing and design. Their ability to provide a reliable guide for straight lines and right angles makes them invaluable in various fields, including architecture, engineering, interior design, graphic design, drafting, education, art, and fashion design. The precision and consistency they offer help professionals and students alike create accurate and professional-quality work.
