Use the Protractor to measure angles and draw arcs. From the Tools Menu, select Maths Tools > Protractor. You can have more than one protractor. The default colours are grey / black. To change the colour of rulers and protractors, select File > Settings > Tools. The colourchanges are shown in the next ruler or protractor you select. The right-click Popup Menu gives options for the protractor and arc drawn. |
|
When you are ready to draw, hover with the pen near the edge of the protractor. The cursor jumps or snaps to the protractor. Click and drag along the edge of the protractor, and a perfect arc will be drawn. The three different arc styles are shown on the right. |

The angle is viewed from the scale on the protractor (zoom in for greater accuracy). |
