Step 1. We draw the inclined rectangle, its parties have to be parallel each other. We draw slightly pressing a pencil since we will erase these lines at achievement of result. In internal part we draw straight lines parallel to each party of a rectangle.

Step 2. Again we draw parallel straight lines, only as on the picture, we draw two slanting lines on corners.

Step 3. We take a pencil more fatly or it is simply more feasibly pressed on it and we lead round the main of doghouses of a rectangle.

Step 4. We draw lines in a rectangle, as shown in the picture.

Step 5. We erase auxiliary lines, here that has to turn out.

Step 6. We paint over.
