Trigon

Trigon is a name that may refer to more than one topic. In mathematics, "trigon" is sometimes used as an informal shorthand for trigonometry—the branch of mathematics that studies the relationships between the angles and sides of triangles. The standard term in education and most literature is trigonometry, and "trigon" is uncommon in formal contexts, appearing mainly in abbreviations, historical texts, or informal notes.

In popular culture, Trigon is a fictional demon in DC Comics, most prominently an antagonist in the Teen Titans series. He is depicted as a powerful demon from an extra-dimensional realm and the father of Raven, one of the Teen Titans. Trigon's narrative centers on his attempts to corrupt or destroy worlds, often through direct confrontation, telepathic influence, and reality manipulation. Across comics, animated adaptations, and other media, the character is typically shown as a formidable, horned, red- or purple-skinned entity wielding vast supernatural powers. His backstory and power set have been elaborated in various runs, and his presence is tied closely to Raven's origin and struggles with her dual heritage.
