## Triangle Stability: 2 (fixes / performance improvements) Triangle is represented as a three coordinates array [A:Vec2, B:Vec2, C:Vec2] * **create** (*x1*: Number, *y1*: Number, *x2*: Number, *y2*: Number, *x3*: Number, *y3*: Number): Triangle A(x1, y1), B(x2, y2), C(x3, y3) * **zero** (): Triangle * **clone** (*tri*: Triangle): Triangle * **copy** (*out_tri*: Triangle, *tri*: Triangle): Triangle * **abMidPoint** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **bcMidPoint** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **caMidPoint** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **midTriangle** (*out*: Beizer, *tri*: Triangle): Triangle * **perimeter** (*tri*: Triangle): Number * **centroid** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **incenter** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **circumcenter** (*out_vec2*: Vec2, *tri*: Triangle): Vec2 * **area** (*tri*: Triangle): Number * **translate** (*out*: Beizer, *tri*: Triangle, *vec2*: Vec2): Triangle * **isVec2Inside** (*tri*: Triangle, *vec2*: Vec2): Boolean * **center** (*out_vec2*: Vec2, *tri*: Triangle) **see**: [centroid](#Triangle-centroid)
