Properties of Parallelograms

1. Change the shape of the parallelogram and notice what happens to the side lengths. Write a conjecture about the side lengths of parallelograms.[br][br]2. Manipulate the figure. Notice what happens to the diagonals. Write a conjecture.[br][br]3. Try to make the parallelogram as close to a rectangle as possible. What do you notice about the diagonals? Write a conjecture.[br][br]4. Try to make the parallelogram as close to a rhombus as possible. What do you notice about the diagonals? Write a conjecture.
