Convert Degrees to Radians

This interactive GeoGebra worksheet allows you to convert degrees to radians. You can vary the angle from -360o to 360o  by moving the slider. The angle (in degrees) is shown to the right of the diagram and the corresponding number of radians is shown below this. Have a go and see what happens!

Note that clockwise angles are taken to be negative and anti-clockwise nagles are taken to be positive.

If you want to return the slider to its original position, then simply click on the icon in the top right hand corner of the worksheet.
