Use the reflection tool to transform ABC exactly onto DEF. When finished, you should have a new triangle A'B'C' that lies perfectly on top of DEF. Hint 1: The 'reflection' tool can be found in the transformations dropdown menu along with other transformations like translations, rotations, and dilations. Hint 2: You may need to write the equation of a line of reflection. You can do this by typing the equation of a line (e.g. x = 2) into the next blank 'Input...' space on the left.
