Equations for solving triangles
WebFrom the small right triangle and from the large right triangle, the following relationships are evident: Substituting the first equation in the second yields: Note that 5′ must be added … In your solving toolbox (along with your pen, paper and calculator) you have these 3 equations: 1. The angles always 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 … See more This means we are given all three angles of a triangle, but no sides. AAA triangles are impossible to solve further since there are is nothing to … See more This mean we are given two angles of a triangle and one side, which is notthe side adjacent to the two given angles. Such a triangle can be solved by using Angles of a Triangle to find the other angle, and The Law of Sines to find … See more This means we are given two sides and the included angle. For this type of triangle, we must use The Law of Cosines first to calculate the … See more This means we are given two angles of a triangle and one side, which isthe side adjacent to the two given angles. In this case we find the third angle by using Angles of a Triangle, then use The Law of Sines to find each of … See more
