7. Let us assume instead that XỶ is limiting parallel to l, with P* X * Y. Prove that PÝ is limiting parallel to l. (Hint: See Figure 6.18. You must show that Pž meets l in a point V. Choose any S such that S+P+Z. Show that SX meets Þó in a point U such that U+P+Q. Choose any W such that UX* W and show that XW is between XÝ and XŘ so that XW meets I in a point T. Apply Proposition 3.9(a) to get V.) X z Y w Q VR т Figure 6.18
