Flexibility: The workspace offers 6 preset lengths and a moveable protractor. The legs and protractor snap to the black spots, allowing legs to be joined and precise measurements with a protractor. The virtual manipulative can be a little hard to manipulate, especially on smaller screens as the manipulative does not scale for screen size. A video walkthrough of the tool is available here.
User Interfaces: Works with mouse and touchpad. Touch works on tablets and phones, but touch tends not to work on touch Chromebooks or touch laptops. The website may not load on some older iPads.
Browsers: Works with all major browsers
