WebIn 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 comes to the rescue. WebWhen sides “a” and “c” and included angle B is known, the area of the triangle is: Area $= \frac{1}{2}\times ac \times sin\; B$ Consider an equilateral triangle ABC with sides a, b, and c. What are the angles of an equilateral triangle? Each interior angle A, B, and C measures $60^\circ$. Thus, $\angle A = \angle B = \angle C = 60^\circ$.
