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.
