Weba 2 = b 2 + c 2 − 2bc cos(A) b 2 = a 2 + c 2 − 2ac cos(B) c 2 = a 2 + b 2 − 2ab cos(C) But it is easier to remember the "c 2 =" form and change the letters as needed ! As in this … Weba2 = b2 + c2 – 2bc x cos (α) b² = a² + c² - 2ac x cos (β) c² = a² + b² - 2ab x cos (γ) The formula can also differ if you have a right triangle. Its angle between the a and b leg is 90 degrees – with a cosine of 0. In this instance, you reduce the formula to a Pythagorean theorem. a² = b² + c² - 2bc x cos (90°) a² = b² + c²
