The vertices of a quadrilateral abcd are a(4, 8), b(10, 10), c(10, 4), and d(4, 4). the vertices of another quadrilateral efcd are e(4, 0), f(10, -2), c(10, 4), and d(4, 4). which conclusion is true about the quadrilaterals? (5 points)

a. the measure of their corresponding angles is equal.
b. the ratio of their corresponding angles is 1: 2.
c. the ratio of their corresponding sides is 1: 2
d. the size of the quadrilaterals is different but shape is same.
