14. Let It be the on two circles with diameters (AH) and (BH) lies on the line 15. Let l'and I" be two circles that intersect at two distinct points: A and B. Assume (XY) and (X'Y'] are the chords of l' and l" respectively, such that A lies between X and X' and B lies between Y and Y". Show that (XY) || (X'Y'). Hint: This is Exercise 9.14 from the textbook and it was in the homework.
