Web25 nov. 2024 · The sine rule is also valid for obtuse-angled triangles. = for a triangle in which angle A is obtus. We can use the extended definition of the trigonometric functions to find the sine and cosine of the angles 0°, 90°, 180°. Hence the tangent of an obtuse angle is the negative of the tangent of its supplement. WebThe sine rule is applicable in any triangle, if either one side and two angles or two sides and one angle are given. In the second case, the angle must be opposite to one of the two given sides. Otherwise, you need the cosine rule. ! Remember In any triangle, two lengths are related to each other like the opposite sine values.
