Square abcd has coordinates a(−10, 5) , b(10, 5), c(10, 0) , and d(−10, 0) . square a'b'c'd' has coordinates a′(−10,−5),b′(10,−5) , c'(10, 0) , and d′(−10, 0) . square a"b"c"d" has coordinates a′′(−2, −1), b′′(2, −1) , c"(2, 0) , and d′′(−2, 0) .

which transformations describe why squares abcd and a"b"c"d" are similar?

a).square abcd was reflected across the y-axis and then dilated by a scale factor of 5 to form square a"b"c"d"

b).square abcd was dilated by a scale factor of 5 and then rotated 90° counterclockwise to form square a"b"c"d" .

c). square abcd was reflected across the x-axis and then dilated by a scale factor of 1/5 to form square a"b"c"d" .

d). square abcd was dilated by a scale factor of 1/5 and then rotated 90° counterclockwise to form square a"b"c"d"
