Abstract

The utility model relates to a square angle gauge, which mainly consists of a square scale plate (1), a first protractor (2) and a second protractor (3). The square angle gauge is characterized in that the first protractor (2) is connected with the lower half part of the square scale plate (1), and the second protractor (3) is connected with the upper half part of the square scale plate (1). The square protractor can conveniently measure the angle and can also be conveniently used as a graduated scale to draw right angles.

Description

Square angle square
Technical field
The utility model relates to a kind of square angle square.
Background technology
The student often will use ruler and protractor in study, and the effect that general protractor only takes measurement of an angle, general ruler also has only picture straight line and the effect of measuring straight line, in study, also will seem convenient inadequately by other instrument.
Summary of the invention
