Which tool is used to check squareness of a line or dimension and helps mark 90-degree angles?

• A. Try Square
• B. Carpenter's Square
• C. Chalk Line
• D. Hack Saw

Answer: (A)

The tool used to check squareness and mark a 90-degree angle is the try square. It’s built with a precisely machined blade that sits perfectly perpendicular to its stock, so you can lay the blade against a edge and verify that the edge runs true and at a right angle to the surface. You can also use it to lay out a 90-degree line on stock by drawing along the edge of the blade, giving a clean, repeatable reference for cuts. While a carpenter’s square can be used to check 90-degree angles and works on larger pieces or frames, it’s less convenient for small, precise work. A chalk line marks long, straight lines but doesn’t verify or impose a right angle. A hacksaw is a cutting tool rather than a measuring or marking tool.
