You need to label the vertices. You also need to label the side lengths (in cm). Write your name on your new Module 3 book Directions (Part 2) – Make sure to leave space to answer: Look at the two figures. Does this appear to be an enlargement or a reduction? How do you know? ________________________________________________________________________________________________________________________________________________________________________________ Compare Segment AB to A’B’.
