To find the perpendicular distance between them is a difficult problem in analytical geometry. With vectors, it is relatively easy. Let the equations of two such lines be r = r1 + tv1 , r = r2 + t v2 . 3 Lines and Planes 25 Let a on line 1 and b on line 2 be the end points of the common perpendicular on these two lines. 47) with t = t2 . Accordingly ra = r1 + t1 v1 , rb = r2 + t2 v2 . 49) Since rb − ra is perpendicular to both v1 and v2 , it must be in the direction of (v1 × v2 ) . If d is the length of rb − ra , then rb − ra = v1 × v2 d.
