Polygon ABCD is dilated, rotated, and translated to form polygon A′B′C′D′. The endpoints of `bar(AB)` are at (0, -7) and (8, 8), and the endpoints of `bar(A'B')` are at (6, -6) and (2, 1.5). What is the scale factor of the dilation?

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

the answer is b

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
