20 ab has endpoints at (-1, -1) and (-2, -4). its transformation a'b' has endpoints at (-2, -2) and (-4, -8). what type of transformation occurred? are lengths of segments affected by this type of transformation? justify. a) rotation; no; the lengths of the two segments are the same. b) reflection; yes; the length of segment a'b' is longer than the original segment ab. c) dilation by a scale factor of 2; yes; the length of segment a'b' is longer than the original segment ab. d) dilation by a scale factor of 1 2 ; the length of segment a'b' is shorter than the original segment ab.
