Graph a triangle ABC and perform a translation of (x + 4, y − 3) to create triangle A′B′C′. Describe the transformation using words. Make sure you refer to the characteristics and the coordinates. Draw a line through points A and A′ and through points B and B′.
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 C and C′? How do you know?
