Identify all pairs of lines that appear to be perpendicular. Select all that apply. There is a horizontal line s, and two parallel lines p and q which are perpendicular to the line s. The line k and m are crosses each other in a shape of X. Also the point of intersection of line k and m is on the line P and the line k is passes through the point of intersection of the lines q and s. A. k, m B. k, s C. p, s D. q, s E. p, m F. q, k
