Set square with a substantially transparent, triangular base body, characterized in that a circular, freely rotatable angle disc is integrated in the central area of ​​the set square, which has a scale from 0 to 180 degrees.

This utility model relates to the technical field of drawing tools, and particularly to a set square. The present utility model discloses a set square, including a set square body and a backing plate rotatably mounted on the set square body; the backing plate includes an upper backing plate, a lower backing plate, and bolts, with the set square body positioned between the upper and lower backing plates; one side of the upper and lower backing plates is fixed to the set square body via a pivot, and the other side can be locked together; the set square body has circumferentially distributed grooves, and the upper backing plate has elastic posts with protrusions; as the backing plate rotates along the circumferential direction of the grooves, the protrusions can engage with different grooves. It aims to solve the technical problem of insufficient accuracy in angle measurement and line drawing in the prior art.
