Graph a triangle (lmn) and rotate it 180° around the origin to create triangle l'm'n'.
1. describe the transformation using words. make sure you refer to the characteristics and the coordinates.
2. draw a line through points l and l'and through m and m'. what do you notice about the lines you drew? do you think you would notice the same characteristics
if you drew another line through points n and n? how do you know?
