32.1DIn the similaritytransformation of ABCto AEDF, AABC was dilated bya scale factor of [?], reflectedacross the [ ], and movedthrough the translation [ ].-41234F 5-3 -2 -1 0-1AZB-3с-4A.2B. 1/2C. 3D. 1/3

Answer 1

To find out the scale factor we must see that ABC is twice as big EDF, which means that EDF was reduced by half, therefore the scale factor is 1/2

Now we must think about the reflection, it's a reflection across the y-axis, it's like if you fold your paper in half (left to right), see that the point of the triangle continues downwards.

After the reflection, we moved it three units to the right (uses the point F as reference) and two units up, if it helps, try to imagine the F point in the light blue figure, and how many units you must move to fit it in the original F points, if you do you will see that it's (x+3, y+2)
