Triangles that are formed through the relationship of three family members are very important in family systems theory and the analysis of genograms. These triangles represent a particular kind of relationship that can have both positve and negative effects on the family as a system. One of the basic principles of family systems theory is that the family system will naturally seek out homeostasis or some type of balance. When instabilty or conflict is present between two family members, a third family member will often be pulled in to stabilize or solidify the family relations in general. In the example shown below, a triangle has formed between Arnold, Madeline, and Scott. The relationship shown between Arnold and Scott is represented by a double line, which indicates a close but healthy relationship. The relationship between Madeline and Scott, on the other hand, is represented by a triple line, which indicates an enmeshed relationship where the involved members have difficulty differentiating themselves from the other in relationship. Finally, the relationship shown between Arnold and Madeline is represented by a zig-zag line, which indicates conflict. The triangle then includes in its representation both healthy and unhealthy relationships. Scott is also identified as an alcoholic and a "dare-devil." In more traditional forms of psychological theory, Scott would probably be identified as the primary "patient" or "problem" in the family system. However, family systems theory uses tools such as the genogram to show that in situations such as these Scott is better labeled the "identified patient" whose alcoholism and extreme risk-taking are manifestations that are likely to be related to the triangle of relationship between himself, Arnold, and Madeline.
