There are three identities relating to the trigonometric functions that make working with triangles easier:. The area rule states that the area of any triangle is equal to half the product of the lengths of the two sides of the triangle multiplied by the sine of the angle included by the two sides. High marks in maths are the key to your success and future plans. Test yourself and learn more on Siyavula Practice. So far we have only applied the trigonometric ratios to right-angled triangles. We now expand the application of the trigonometric ratios to triangles that do not have a right angle:. Video: G.
