Line A'C' will be twice as long as AC
Line P'Q' will be twice as long as PQ
1) Considering that there was a dilation whose scale factor is k=2, (an enlargement since k > 1).
2) Then we can state that:
Line A'C' will be twice as long as AC
Line P'Q' will be twice as long as PQ
Due to the dilation with a scale factor of 2.
