Note that WXYZ has vertices W(-1, 2), X(-5, 7), y(-1, -2), and Z (3, -7). Answer the following to determine if the parallelogram is a rectangle, rhombus, square, or none of these.
(a) Find the slope of WZ and the slope of a side adjacent to WZ.
(b) Find the length of WZ and the length of a side adjacent to WZ. (Give exact answers, not decimal approximations.)
(c)What can we conclude about parallelogram WXYZ? Check all that apply.
-WXYZ is a rectangle
-WXYZ is a rhombus
-WXYZ is a square
-WXYZ is none of these.
