We 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. Similarly, we can compare the other ratios. sinα a = sin γ c and sinβ b = sinγ c. Collectively, these relationships are called the Law of Sines. fred smith son football coach
