This is an example of a simple book which is meant to show that all real-life objects aren't perfectly geometrical. Although this appears rectangular, the book doesn't have exactly two sets of parallel lines and four right degree angles. The angles are slightly more or less than 90. However, you can see that numbers are very close to the theorems we have studied.

This picture is the same book at a different angle. You can see that front the top it appears to be a rectangle(above), but when it is taken from a slightly different angle things change. Due to perspective, the book looks a trapezoid. There is one set of parallel lines because angle FGJ and angle GJI are supplementary. The same thing applies with angle IFG and angle JIF. (~SV1)
