To assist me in finding a neat method, can you tell me what exercise this came under. Was it perpendicular distance, k-method, properties of quadrilaterals, .......... ?

This chapter covers the perpendicular distance. It hints saying that the distance between two intercepts of one pair of lines must equal the distance between the y inc on other pair?
