A try square is a measuring tool used in woodworking to ensure that corners are perfectly square. There are several synonyms for this tool, including a framing square, a carpenter's square, and a speed square. A framing square is typically larger than a try square, and is used for larger projects like framing a house. A carpenter's square is very similar to a try square and is often used interchangeably in woodworking. A speed square is a specialized type of square that has additional features, such as a protractor and a measurement guide for cutting angles. Regardless of which synonym you use, a square is an essential tool for woodworking and precision cutting.
