Which statement is true about quadrilateral abcd with vertices a(2, 8), b(3, 11), c(4, 8), and d(3, 5)? a) quadrilateral abcd is a square because adjacent sides have slopes that are negative reciprocals. b) quadrilateral abcd is a rhombus because adjacent sides have slopes that are negative reciprocals. c) quadrilateral abcd is a square because adjacent sides have slopes that are not negative reciprocals. d) quadrilateral abcd is a rhombus because adjacent sides have slopes that are not negative reciprocals.
