What is incongruent?

Incongruent can refer to things that do not fit together or match up harmoniously. In mathematics, an incongruent triangle is a triangle that has different side lengths and/or angles than another triangle. In psychology, incongruence can refer to a discrepancy between a person's self-image and their actual behavior or experiences, which can cause distress or disharmony. Incongruity is often used as a literary device in humor, where unexpected, odd, or jarring elements are juxtaposed to create a surprising or absurd effect.
