TSquares are commonly used in construction and engineering industries to draw straight lines and ensure accurate angles. Synonyms for TSquares include drafting squares, engineers squares, L-squares, and angle squares. Drafting squares are typically used for more precise and detailed work, whereas engineering squares are used for larger surfaces and measurements. L-squares are named due to their shape and are often used in woodworking and metalworking. Whilst angle squares are designed to measure angles instead of drawing lines, they are still considered a synonym for TSquares due to their similar function. Regardless of which synonym you use, these tools are essential to maintaining accuracy and precision in various industries.
