如何用四條直線把九點連在一起??急...20分

在第一行第一個點開始(簡稱1.1)到1.3的右小小，直到能夠直穿2.3and3.2，之後繼續延長至在1.1and1.3連結的線上，然後穿過3.1,2.1,1.1，在1.1處停，然後穿到2.2,3.3

我們這樣開始：
1 2 3
a‧‧‧
b‧‧‧
c‧‧‧
把1a, 2b, 3c連線

Trust me!!! I didn't answer this question by coping from the internet. I TYPE THE WHOLE THING MYSELF!!! I UPLOADED THE PICTURES IN PHOTO BUCKET IN MY ACCOUNT!!! I FOUND THIS QUESTION IN THE SCIENCE MUSEUM IN TORONTO WHEN I WAS 8 YEARS OLD!!!

First we name 16 dots on a 4 * 4 plot (Yes. 4*4)

1 2 3 x
4 5 6 y
7 8 9 z
a b c d

Your goal is to connect the dots 1-9 using four straight lines.
The four lines are:
123x
x68a
a741
a59
