1) Explain the shift if you add three to the x coordinate and subtract 1 from the y coordinate. What type of transformation is this? Would this image remain congruent to the pre-image?
2) The original coordinates of a triangle are (1,1) (4,1) (4,5). The new coordinates are (1, -1) (4, -1) and (4,-5). What happened to this triangle? What type of transformation took place and how do you know?
3) Explain how the coordinates change in a 90 degree counterclockwise rotation. What stays the same?
4) When a figure is dilated by a factor of 3 how do the coordinates change. Is your new figure still congruent if not, explain the relationship between the two.
