Jun 5, 2023 · 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. Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides: x 2 + y 2 = 1 2. But 1 2 is just 1, so: x2 + y2 = 1. equation of the unit circle.
