APPENDIX

Worksheet 1
a. Construct a dynamic kite using the properties of kites explored and discussed in our previous lessons.
b. Check to ensure that you have a dynamic kite, i.e., does it always remain a kite no matter how you transform the figure? Compare your construction(s) with those of your neighbors--is it the same or different?
c. Next construct the midpoints of the sides and connect the midpoints of adjacent sides to form an inscribed quadrilateral.
d. What do you notice about the inscribed quadrilateral formed in this way?
e. State your conjecture.
