x1 is aligned diagonally along/between nonadjacent vertices x2 as in polytope x3; x1 is a diagonal line segment/linear manifold of lower dimension as viewed in frame of reference x3; x1 is crooked (one sense), skew (one sense, see notes), off-kilter (one sense), away from center/off-center, non-orthogonal/not perpendicular nor parallel, at an angle, perhaps non-vertical and non-horizontal, diagonal to x2 in figure/coordinate system x3.
x1=sr1=m1=se2 errs in being identical to x2=m2 (object/person), an error under conditions x3=sr3 by standard x4=sr4=m3; x1 loses themselves in being x2; x1 errs in being a clone, caricature of x2; x1 has an identity crisis, typecasts themselves.
