This 19-minute mathematics video explores why the Pythagorean theorem is limited to right triangles and introduces more versatile alternatives for solving general triangles. Learn how the law of cosines and the law of sines provide robust solutions when dealing with non-right angles, including the challenging ambiguous case of SSA (Side-Side-Angle). Follow along as the presenter breaks down the process of solving triangles, demonstrates practical applications of these trigonometric laws, and explains when to use each method. The video progresses from basic triangle-solving concepts to handling complex ambiguous cases, making advanced geometric principles accessible to mathematics enthusiasts.
