Ab has endpoints at (-9, 12) and (3, -6). its transformation a'b' has endpoints at (-3, 4) and (1, -2). what type of transformation occurred? are lengths of segments affected by this type of transformation? justify. a) reflection; no; the lengths of the two segments are the same. b) rotation; yes; the length of segment a'b' is longer than the original segment ab. c) dilation by a scale factor of 3; yes; the length of segment a'b' is shorter than the original segment ab. d) dilation by a scale factor of 1 3 ; yes; the length of segment a'b' is shorter than the original segment ab.
