WebThe law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non- right triangle, each angle of the triangle has the same … WebUsing the right triangle relationships, we know that sinα = h b and sinβ = h a. Solving both equations for h gives two different expressions for h. h = bsinα and h = asin β. 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.
