Can law of sines work on right triangles
WebFeb 10, 2024 · c² = a² + b² - 2ab × cos (γ) For a right triangle, the angle gamma, which is the angle between legs a and b, is equal to 90°. The cosine of 90° = 0, so in that special case, the law of cosines formula is reduced to the well-known equation of Pythagorean theorem: a² = b² + c² - 2bc × cos (90°) a² = b² + c².
