Protractor and Ruler

The ruler and protractor, appearing as draggable, partially transparent objects, are used to "measure" lengths or angles of other images shown on screen, built into the Question/Item content. 

Like the Calculator, the Protractor and the Ruler are accessed via a button for the learner, that when clicked will display the tool.
