Properties of Parallelograms Part 2
What do you notice about the opposite sides of the parallelogram?
What do you notice about its consecutive angles?
What do you notice about its opposite angles?
What do you notice about its diagonals?
Can you create a parallelogram that is a counterexample to any of your conjectures above? Provide justification why or why not?
Using your answers above, create a list of the properties of all parallelograms. Make sure to add that opposite sides are parallel, a property you learned way back when.
