Webb27 jan. 2016 · To find a triangle’s height, you measure the length of a line segment that starts at one corner—a vertex —and meets the opposite side—the base —at a 90º angle. You’re probably used to drawing a height line on the inside of a triangle that runs from the top corner to the bottom side. WebbLet’s work out a couple of example problems based on the sine rule. Example 1. Given that sine (A) = 2/3, calculate angle ∠ B as shown in the triangle below. Solution. Since we are asked to calculate the size of an angle, then we will use the sine rule in the form: Sine (A)/a = Sine (B)/b. By substitution,
