Try square

Try square

A try square is a woodworking or a metal working tool used for marking and measuring a piece of wood. The "square" refers to the tool's primary use of measuring the accuracy of a right angle (90 degrees); to "try" a surface is to check its straightness or correspondence to an adjoining surface. A piece of wood that is rectangular, flat, and has all edges (faces, sides, and ends) 90 degrees is called four square. A board is often milled four square in preparation for using it in building furniture.

Try square is sometimes spelled "tri-square", or referred to as a combination square.

A traditional try square has a broad blade made of steel or brass that is riveted to a wooden handle. The inside of the wooden handle typically has a steel or brass strip fixed to it that is precisely 90 degrees to the blade. Some blades have either metric or English graduations for measurement.
