T-squares

T-squares are tools commonly used in drafting and technical drawing. They consist of a long, straight edge (the blade) and a shorter perpendicular edge (the head) shaped like a "T." The blade allows for precise, straight lines, while the head helps ensure right angles, making it easier to create accurate geometric shapes and layouts. T-squares are essential in architecture, engineering, and design, providing a reliable way to guide a pencil or cutting tool for clean, professional-looking drafts. Their design promotes stability and accuracy, important for producing technical drawings and plans.
