Calculator Use A right triangle is a special case of a triangle where 1 angle is equal to 90 degrees. In the case of a right triangle a 2 + b 2 = c 2. This formula is known as the Pythagorean Theorem. In our calculations for a right triangle we only consider 2 known sides to calculate the other 7 unknowns.

Angles Add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3.

In mathematics, the Pythagorean theorem or Pythagoras' theorem is a fundamental relation in Euclidean geometry between the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides.
