What tool is used to mark out precise angles on a workpiece?

A protractor is specifically designed to measure and mark angles on a workpiece, making it the ideal tool for tasks that require precise angle measurements. Its semicircular format allows the user to easily see the degree markings, which can then be used to accurately set and transfer angles onto materials. This precision is crucial in carpentry, where even minor deviations can affect the fit and finish of a project.

While a measuring tape is essential for measuring linear distances, it lacks the capability to determine or mark angles. A square, particularly a framing or speed square, is primarily used for ensuring straight lines, 90-degree angles, and for making quick angle cuts, but it does not provide the same flexibility for measuring various angles as a protractor. A level is used to check horizontal or vertical alignment, but does not assist in marking angles at all.
