WebbIn 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. WebbIf you split the equilateral triangle down the middle, you produce two triangles with 30°, 60° and 90° angles. These two right triangles are congruent. They both have a hypotenuse of length 2 and a base of length 1. You can determine the height using the Pythagorean Theorem. Here is the left half of the equilateral triangle turned on its side.
