Questions to Discuss

You will need to create a parallelogram with diagonals. Please work in pairs for discussions. Add the diagonals, manipulate the diagram, and make observations.  I encourage you to display angle and side measures to try to determine relationships.  Discussion: What happens as you drag a vertex?  Which measurements change?  Which stay the same?
