PLEASE HELP !! Use the diagram and given information to answer the question.
Given: △ABC∼△CDE BC¯¯¯¯¯¯¯¯ and CD¯¯¯¯¯¯¯¯ are horizontal segments. AB¯¯¯¯¯¯¯¯ and ED¯¯¯¯¯¯¯¯ are vertical segments. Lines l and m are perpendicular. Prove: Lines l and m have slopes that are opposite reciprocals. What description shows that lines l and m have slopes that are opposite reciprocals?
A) The triangles are similar, so ABBC=CDDE. The slope of l=ABBC and the slope of m=−DECD. Since CDDE and −DECD are opposite reciprocals, lines l and m have slopes that are opposite reciprocals
. B) The triangles are similar, so BCAB=DECD. The slope of l=BCAB and the slope of m=−CDDE. Since DECD and −CDDE are opposite reciprocals, lines l and m have slopes that are opposite reciprocals.
C) The triangles are similar, so BCAB=DECD. The slope of l=−ABBC and the slope of m=DECD. Since BCAB and −ABBC are opposite reciprocals, lines l and m have slopes that are opposite reciprocals
. D) The triangles are similar, so ABBC=CDDE. The slope of l=−BCAB and the slope of m=CDDE. Since ABBC and −BCAB are opposite reciprocals, lines l and m have slopes that are opposite reciprocals.
