$Delta A'B'C' ?$

$m ang B'A'C' = m ang BAC^2 , \ m ang A'B'C' = m ang ABC ^2, \ m ang A'C'B' = m ang ACB ^2$
$m ang BAC = 2m ang B'A'C', \ m ang ABC = 2m ang A'B'C', \ m ang ACB = 2m ang A'C'B'$
$m ang BAC = m ang B'A'C', \ m ang ABC = m ang A'B'C', \ m ang ACB = m ang A'C'B'$
$m ang BAC = 1/3 m ang B'A'C', \ m ang ABC = 1/3 m ang A'B'C', \ m ang ACB = 1/3 m ang A'C'B'$

The results in the previous two questions would only be altered if another dilation were added to the sequence of transformations. Otherwise, there would be no change.
Adding any one of the additional transformations would affect the results in the previous two questions.
None of the additional transformations, if added to the sequence of transformations, would affect the results in the previous two questions.
Adding additional transformations would only affect the results in the previous two questions if they included a transformation not around the origin (such as a rotation about a point that is not the origin, or a dilation not centered at the origin).
