Answer:
Reflect across BC
Translate 4 units right
Translate 1 units down
Step-by-step explanation:
In order to receive DEF, you need to flip it across line BC. In order to find this out, just test what would happen if you flipped on the other sides. If you did that correctly, the other sides wouldn't be shaped the same as DEF.
Remember, translation is moving the ENTIRE triangle. Not just one particular point. In order to line up the two shapes correctly, you have to move the shape down one unit and across four units. To find this, you can simply just count it out. Remember, C has to reach to F. B has to reach to E. And A has to reach to D. Once you find how much you translate the graph, then you've found the answer.
