Open Middle: Building Trapezoids

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 trapezoid
Note: Repeated coordinates, if any, are displayed to the right.

Create a trapezoid 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 trapezoid. Be sure to fully explain your reasoning!

Create another trapezoid 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 trapezoid. Be sure to fully explain your reasoning!
