EXTENSION: Quadrilaterals on the Coordinate Plane
Can you build specific quadrilaterals without dragging the vertices (corners)?
Try to build examples of the following classes of quadrilaterals just by plotting the corner points on the coordinate plane:
* square
* rectangle
* parallellogram
* what shape is next?
What do you notice about the coordinates in each of these examples? Can you come up with general rules?
