Side length of triangle rule
Websin (A) < a/c, there are two possible triangles. solve for the 2 possible values of the 3rd side b = c*cos (A) ± √ [ a 2 - c 2 sin 2 (A) ] [1] for each set of solutions, use The Law of Cosines to solve for each of the other two angles. present 2 full solutions. Example: sin (A) = a/c, there is one possible triangle. WebThe length of the sides of that triangle will be sin α, sin β and sin γ. The side whose length is sin α is opposite to the angle whose measure is α, etc. The law of cosines, or cosine rule, connects the length of an unknown side of a triangle to the length of the other sides and the angle opposite to the unknown side. As per the law:
