PROBLEM: Sum of angles of a triangle -- In several geometries, a triangle has three vertices and three sides, where three angles of a triangle are formed at each vertex by a pair of adjacent sides. In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180°, π radians, two right angles, or a half-turn.

SOLUTION: do all angles on a triangle add up to 180

PROBLEM: Damon Salvatore -- Damon Salvatore is a fictional character in The Vampire Diaries novel series. He is portrayed by Ian Somerhalder in the television series. Initially, Damon is the main antagonist in the beginning of the show and later became a protagonist. After the first few episodes, Damon begins working alongside his younger brother, Stefan Salvatore, to resist greater threats and gradually Elena begins to consider him a friend. His transition was completed after his younger brother Stefan, who is also a vampire, convinces him to drink blood. Damon thus vows to make his brother's life sorrowful -- thus further causing a century-long rift between the two brothers, centering around Katherine and eventually a love triangle with Elena Gilbert. After on-again/off-again relationship with both brothers, Elena chooses to be with Damon in the series finale.
