Claims

[Scope of utility model registration request]

As shown in the drawing, the reference point for measuring angles is placed on the edge or corner of the length scale, with the length scale on one side of the ruler and the angle scale on the other sides. A protractor with a ruler configured as above that can measure angles and draw lines at the same time.
