A try square is a woodworking or a metalworking 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.
