Step-by-step explanation:
The analogy used to explain Lee's six styles of loving is a triangle. According to Sternberg's triangular theory of love, love can be described by the combination of three components: intimacy, passion, and commitment. These three components form the three sides of a triangle, with different combinations representing different styles of loving. For example, consummate love is represented by a triangle with all three components present, whereas infatuation may be represented by a triangle with only passion present.
