三角不等式
1. Triangle inequalityIn mathematics, the triangle inequality states that for any triangle, the sum of the lengths of any two sides must be greater than or equal to the length of the remaining side (and, if the setting is a Euclidean space, then the inequality is strict if the triangle is non-degenerate). In Euclidean geometry and some other geometries the triangle inequality is a theorem about distances.
