Here is a quadrilateral that is said to be a trapezoid. (Be sure to drag A, B, C, D around).
Without Googling, complete the following sentence definition: A trapezoid is a quadrilateral with ...
YOUR TASK:
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
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!
