Discovering Properties of Parallelograms

Below is a parallelogram. To discover the properties of ALL parallelograms do the following:
  1. Using the segment tool, create diagonals of the parallelogram
  2. Measure the distance of the diagonals, sides, and from the point of intersection to each vertices
  3. Measure the angles measurements
  4. Move your parallelogram around . . . do your properties stay true?
