△klm is reflected to form △ k ′ l ′ m ′ . the vertices of △klm are k(2,4) , l(1,2) , and m(4,1) . the vertices of △ k ′ l ′ m ′ are k ′ (4,2) , l ′ (2,1) , and m ′ (1,4) . which reflection results in the transformation of △klm to △ k ′ l ′ m ′ ? reflection across the x-axis reflection across the y-axis reflection across y = x reflection across y=−x
