Since the dilation is centered at vertex A, the coordinates of A' are the same of A.

Then, to find the coordinates of B, let's multiply the distance AB by the scale factor:


\begin{gathered} AB=12.6\\ \\ A^(\prime)B^(\prime)=12.6\cdot(1)/(4)=3.15 \end{gathered}

Doing the same for AC, we have:


A^(\prime)C^(\prime)=AC\cdot(1)/(4)=11.3\cdot(1)/(4)=2.825

The points B' and C' are on the sides AB and AC, respectively.

Knowing this, let's draw the image A'B'C':

Since AB = BC, we also have A'B' = B'C' = 3.15.
