The tribar,or Penrose triangle,is an impossible object which appears to be three straight beams of square (or,in this case,beams of squares) cross-section which meet pairwise at right angles at the vertices of the triangle they form. This combination of properties cannot be realized by any actual 3-dimensional object | |
