The steel square is a tool used in carpentry. Carpenters use various tools to lay out structures that are square (that is, built at accurately measured right angles), many of which are made of steel, but the name steel square refers to a specific long-armed square that has additional uses for measurement, especially of various angles.
It consists of a long, wider arm and a shorter, narrower arm, which meet at an angle of 90 degrees (a right angle). It can also be made of aluminum or polymers, which are light and resistant to rust.
The longer wider arm is two inches wide, and is called the blade; the shorter narrower arm, is one and a half inches wide, and is called the tongue. The square has many uses, including laying out common rafters, hip rafters and stairs.
