Artists find mind-bending ways to bring impossible figures into three-dimensional reality In an impossible figure, seemingly real objects—or parts of objects—form geometric relations that ...

One of these figures is the Penrose Triangle, also known as the Tribar. This object, considered an “impossible figure”, is formed by three bars that appear to connect at right angles, forming a ...

And depending on the manner in which geometric information is presented, interpreting objects in the exact way a teacher intended may be next to impossible. Consider the two figures shown below.
