Knowing the points a(−5, 2), b(3, 4), c(−4, −3), and d(4, −1), and that segment ab parallel to segment cd, what is the length of segment ab and segment cd, and do points a, b, c, and d form a parallelogram?
a) ab=8 and cd=8; therefore, abcd is a parallelogram
b) ab=2sqrt17 and cd=2sqrt17; therefore, abcd is a paralleogram
c) ab=4sqrt5 and cd=4sqrt5; therefore, abcd is a parallelogram
d) ab = 2sqrt17 and cd=4sqrt5; therefore, abcd is a parallelogram
