How do you draw a house without lifting your pencil?

Answer 1

You start out at the bottom left corner, then draw a line diagonally up to the upper right corner. Now that you're at the top, draw a straight line and end it right above the point where you started. Draw another diagonal line down to the bottom right corner, opposite the starting point. Draw a line upwards up to the top right corner, then draw a triangle above the square without lifting the pencil, and finally, draw a straight line down and then across to finish the square. There are many other ways to do this by reversing the technique, etc.

I hope this makes sense. It's difficult to explain without showing it to you.
