Task 2

 

A Path Puzzle 2

 

The illustration shows eight houses and their front doors. The problem is to draw a line from the door of A to the door of another line that joins the doors of B and B', a third line that joins C to C', and a fourth that joins D to D'. No line may cross another line, pass through the sides of a house, or cross the outside rectangular border of the picture. The problem may seem impossible to solve, but it can be done.
