Things are not what they look like.
You have to use logic to find the truth.
What do you see in the above picture?
(a) a cube with the lower-left square as its front side
(b) a cube with the upper-right square as its front side
(c) a configuration of twelve line segments
Use logic to find the truth. Hint: The picture is two-dimensional.
Don’t believe what you are shown. Don’t believe what you are told. Use your mind. Most of the time, the obvious choice is not the truth.
