Abstract

The utility model relates to a plotting and measuring tool, in particular to a ruler which integrates a straight scale, a protractor and a set square. The upper portion of the ruler is the straight scale, the left lower portion of the ruler is the inverted protractor, and the right lower portion of the ruler is the right angle set square. Degree scales of per unit length are arranged on the edge of the straight scale, and the degree scales of per unit length are also arranged on two right angle edges of the right angle set square. Two ends of the straight scale on the upper portion are in an arc shape. The ruler is simple in structure, small in size, and convenient to carry. The ruler can be used for drawing straight lines and right triangles and measuring angles.
