Splet16. mar. 2024 · Theorem (Law of Cosines). c^2 = a^2 + b^2 - 2ab Cos [C]. Proof. Place triangle ABC on a Cartesian coordinate system such that angle C is at the origin and length a lies on the x-axis. Then length b is on the other ray from the origin. We can easily identify the coordinates of two of the vertices: Vertex C lies at (0,0), and vertex B lies at (a,0).
