You can drag around all four corners of the quadrilaterals. Look in the upper left corner - if your quadrilateral has a name, the name will pop up there in green! For example, when you open this, it should say "parallelogram, rectangle, square" in the upper right hand corner. Below those are two checkboxes. If you check those, you can toggle angle measurements and diagonals on and off. Finally, below that highlighted in yellow are the lengths of the diagonals. Use all of this information to complete the worksheet that was handed out!
