This optical illusion drawing is sure to fool your eyes. Look at the
two distances AC and AB. AC appears to be much longer than AB at first
glance because of the perspective that is drawn into this picture. In
addition, the sizes of the trees actually get smaller the farther back
in the picture you go.
As you most likely guessed, the two lines are exactly the same length.
ALSO the second part of this illusion is that if you were to judge
the angle of CAB above, would you think it was about 45 degrees, 75
degrees, 90 degrees, or other? The answer is other. This is because
the actual angle is slightly greater than 90 degrees. To test this,
place a piece of paper next to the screen and you'll se that it easily
fits into the angle created by the three lines.
