The geometry club designed a new shirt for club members. The pocket is formed by a rectangle with vertices at R(2, 1), S(10, 1), T(10, 10), and U(2, 10). The geometry club logo will be placed on a quadrilateral formed by connecting the midpoints of the sides of the rectangular pocket. a. Find and label the coordinates of the vertices of the interior quadrilateral. b. Make a conjecture to classify the interior quadrilateral that will be used for the geometry club logo using lengths and slopes of the sides.
