6-6 Placing Figures in the Coordinate Plane L.E.Q. How do you use properties of special figures to name missing coordinates?
Example 1: Naming 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.
Example 2: Real-World Connection. • 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.
Homework: • Pgs. 328 – 329 #s 1 – 6, 28 – 30.
