Law of Sines: Definition, Formula, Examples & Proof

WebSep 15, 2024 · The angle between two sides of a triangle is often called the included angle. Notice in the Law of Cosines that if two sides and their included angle are known (e.g. \(b \), \(c \), and \(A\)), then we have a formula for the square of the third side. We will now solve the triangle from Example \(\PageIndex{2}\). WebWe then set the expressions equal to each other. bsinα =asinβ ( 1 ab)(bsinα)= (asinβ)( 1 ab) Multiply both sides by 1 ab. sinα a = sinβ b b sin α = a sin β ( 1 a b) ( b sin α) = ( a sin β) ( 1 a b) Multiply both sides by 1 a b. sin α a = sin β b. Similarly, we can compare the other ratios. WebLet us look at some worked examples that apply the Law of Sines. Solving a Triangle Given Two Angles and a Side.
