H and P are located at (-8,7) and (-2,-3) (note, they are interchangeable) 24. nswers will vary depending on method chosen to prove parallelogram and then rectangle. Examples: 1 st prove parallelogram: o Since the slopes of & = -1 and the slopes of & =1, then and. Since both sets of opposite sides are, then quadrilateral is a parallelogram. o Since = 2 2 = and = 9 2 =, then and. Since both sets of opposite sides are congruent, then quadrilateral is a parallelogram. o Since the midpoints of & are both (2.5, -1.5), then the diagonals bisect each other so quad is a. 2 nd prove rectangle: o Since the slopes of =1 & =-1 are opposite reciprocals, then. Since is a right, then parallelogram is a rectangle. o Since = 170 =, then. Since the diagonals are congruent, then parallelogram is a rectangle. 25..
