WebAnother way to find the area of a triangle when you know the lengths of all 3 sides is to use Heron's Formula. Heron's formula states that: Area = √ (s (s-a) (s-b) (s-c)) Where s is the semi-perimeter of the triangle, which is the sum of the three side lengths divided by 2, and a, b, and c are the lengths of the three sides of the triangle. WebFeb 7, 2012 · If we know the measures of two angles, we can find the measure of the third angle using A + B + C = 180 °, so let's assume we know all three angle measures A, B, and C, and the side length a. We can use the Law of Sines to find each of the unknown side lengths: b = a sin B sin A c = a sin C sin A SSA
