Entering an Angle
- Click the angle field under the controls section to enter a new angle.
- You may enter any number into the angle field (e.g. 270), and it will be interpreted in degrees.
- If you include the keyword pi anywhere in your input (e.g. 3*pi/2), the angle will be interpreted in radians.
- You may also click anywhere in the drawing to form an angle (based on where you clicked).
