4.2 Exploration, example 6
Directions
For problems #5 & 6, use the coordinate reflection rules from earlier parts of the activity to find the coordinates of the image of triangle ABC. After, use the applet to graph the line of reflection and the image to check your answer.
Line of reflection: y = -x
Write down the coordinate rule for this reflection:
