                The LAW of COSINES is used to solve oblique triangles in which two sides and the included angle (SAS)are given or three sides (SSS) are given. 					
					
For any ∆𝐀𝐁𝐂 with angle measures A, B, C and side lengths a, b, c
					
STANDARD FORM
a²= b²+c²-2bcCos A
b = a²+c²-2acCos B
c²=a²+b²-2abCos C
