Math teachers often need to draw a 30 degrees, 45 degrees, or other angle of the line in the teaching process. It is troublesome to do it with the traditional teaching ruler. This design can help you draw these lines simply by just rotating it and you will find the line of whatever the angle you want. Teaching will be more efficient in the class.
