1. List the vertices of the image of ∆ABC after the translation (x, y)→(x + 3, y – 2) is applied. Vertices of ∆ABC are A(4,5), B(-3, 4), C(2, -1).
2. What is the image of the point A(2, 5) first reflected over y = 5, then reflected over x = -2. (1 point first reflection, 1 point second reflection)
3. What is the image of N after a 135° rotation about O? What angle of rotation maps LM to PR? (2 points)
4.5. What type of symmetry does the figure have? If line symmetry, show the lines of symmetry. If rotational symmetry, provide the angle of rotation. If both, please include both.

$$\large\rm (x,y)\qquad\to\qquad (x+3,~~y-2)$$Apply this rule to vertex A,$$\large\rm A(4,5)\qquad\to\qquad A'(4+3,~~5-2)$$So where is your new A located? :)
