PENROSE TRIANGLE

a 3-D impossible shape consisting of three bars, each at right angle to the adjacent bar, which seem to make a twisted triangle. The shape is more correctly referred to as a tribar, since authentic triangles have three angles which add up to 180

PENROSE TRIANGLE: "The concept of the penrose triangle seemed to please my geometry teacher far more than it did any of the students."
