The Perverse Triangle was first described in 1977 by Jay Haley [6] as a triangle where two people who are on different hierarchical or generational levels form a coalition against a third person (e.g., "a covert alliance between a parent and a child, who band together to undermine the other parent's power and authority".) [7] The perverse triangle concept has been widely discussed in ...
A 180° rotation (middle) followed by a positive 90° rotation (left) is equivalent to a single negative 90° (positive 270°) rotation (right). Each of these figures depicts the result of a rotation relative to an upright starting position (bottom left) and includes the matrix representation of the permutation applied by the rotation (center ...
Animation of a half-turn ambigram of the word ambigram, with 180-degree rotational symmetry [1]. An ambigram is a calligraphic composition of glyphs (letters, numbers, symbols or other shapes) that can yield different meanings depending on the orientation of observation.
We can also define the number of triangles that vertex is involved in as () and, as each triangle is counted three times, we can express the number of triangles in G as () = (). Assuming that triadic closure holds, only two strong edges are required for a triple to form.
The Malan triangles are considered main components of Experiential Short-Term Dynamic Psychotherapy (E-STDP), along with mirroring function and dynamic activities. [8] They are also employed as vade mecum in introducing the principles and practice of dynamic therapy to trainee therapists or experienced professionals who need to "unlearn" the ...
