An online activity to help students identify quadrilaterals by characteristics
rather than appearance. The original Sketchpad file: quads.gsp
When this page is loaded, each quadrilateral looks like a square. But as you drag the vertices, the quadrilateral's true nature is revealed. Your job is to find the most specific name for each that is always true.
