The articulating angle is an adjustable measuring and drawing tool consisting of a handle, or jib, and a movable steel arm. The two parts are connected by a joint with a locking mechanism, most commonly a wing nut or bolt. Its key feature is that it allows a completely arbitrary angle to be set and fixed, because unlike conventional angles it has no fixed stop for preset values such as 90° or 45°. The main use of this tool is in transferring and copying non-standard angles. The workflow is to attach the angle to an existing angle, for example in a corner of a room or on a workpiece, set the arm precisely to it and then secure the position by tightening the nut. The "locked" angle can then be faithfully transferred and traced onto another material that needs to be accurately cut or otherwise adjusted. It is therefore not primarily used to determine the value of the angle in degrees, but to physically copy and replicate it.
