In the similaritytransformation of AABCto ADFE, AABC was dilated bya scale factor of [?], reflected5 across the [ ], and movedthrough the translation [ ].
We are transforming triangle ABC to DFE. If we see the graph, we can see the measures of each side of the triangle, decrease by half. According to that, it would be 1/2 of the original measure.
