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.

Given two sides If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem: a² + b² = c² If leg a is the missing side, then transform the equation to the form where a is on one side and take a square root: a = √ (c² - b²) If leg b is unknown, then: b = √ (c² - a²)

The perimeter of a triangle is equal to the sum of all the sides of the triangle, and the formula is expressed as, Perimeter of a triangle formula, P = (a + b + c), where 'a', 'b', and 'c' are the three sides of the triangle. The equilateral triangle formula for perimeter is, Perimeter of equilateral triangle = (a +a + a) = 3a.

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.

The Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C).
