Triangles triangle klm and triangle abc are congruent. The side length of each square on the grid is 1 unit. Triangle abc has point a at (8, 8), point b at (10, 6), and point c at (4, 6). Triangle klm has point k at (11, 9), point l at (13, 7), and point m at (13, 13). Which of the following sequences of transformations maps triangle klm onto triangle abc?
1) Only sequence a ________. A translation 9 units to the left and 7 units down, then a reflection over the line with slope -1 through point c.
2) Only sequence B: A reflection over the line kl, then a translation 3 units to the left and 1 unit down.
3) Both sequence A and sequence B.
4) Neither sequence A nor sequence B.
