Triangle ABC has vertices A(3, 1), B(3, 4), and C(7, 1).

1. Part A: If ABC is translated according to the rule (x, y) (x 4, y + 3) to form A'B'C', how is the translation described with words? (3 points)
2. Part B: Where are the vertices of A'B'C' located? Show your work or explain your steps. (4 points)
3. Part C: Triangle A'B'C' is rotated 90 clockwise about the origin to form A"B"C". Is ABC congruent to A"B"C"? Give details to support your answer. (3 points)
