L.E.Q. How do you use properties of special figures to name missing coordinates?

 In the diagram, rectangle KLMN is centered at the origin with sides parallel to the axes. Find the missing coordinates of K, M, and N.

 Use the properties of parallelogram OPQR to find the missing coordinates. Do not use any new variables.

 An art class creates T-shirt designs by drawing quadrilaterals, connecting their midpoints to form other quadrilaterals, and then coloring the regions. Tiana claims that everyone’s inner quadrilateral will be a parallelogram. Is she correct? Explain.

 Use a different method to show that TWVU is a parallelogram by finding the midpoints of the diagonals.

 Pgs. 328 – 329 #s 1 – 6, 28 – 30.
