Open Middle: Building Parallelograms

The quadrilateral below has 4 vertices. Each vertex has 2 coordinates (x, y). Your task: Construct a quadrilateral in the app below so that
  • Coordinates take on integer values 0 - 9
  • There are no repeated coordinates
  • The quadrilateral formed is a parallelogram
Note: Repeated coordinates, if any, are displayed to the right.

Create a parallelogram below. Be sure the vertices have no repeated coordinates!

Use any GeoGebra tool(s) in the app above to clearly show how you know the quadrilateral you just formed is a parallelogram. Be sure to fully explain your reasoning!

Create another parallelogram different from the one you created above. Be sure the vertices have no repeated coordinates!

Use any GeoGebra tool(s) in the app above to clearly show how you know the quadrilateral you just formed is a parallelogram. Be sure to fully explain your reasoning!
