Angle ruler

Ruler

This is a drawing tool that combines the protractor and the ruler. When students draw, they usually need a device for calculating angles and a ruler, two separate tools. The Angle Ruler combines these two tools and functions. To draw an angle, the user draws a line from the endpoint of the zero scale line. They select the angle they need in the angle scale and mark it. In the last step, the endpoints are connected to draw the angle.
