Measurement and Geometry : Module 24 Year : PDF Version of module. In the module, Introductory Trigonometry , we showed that if we know the angles and one side in a right-angled triangle we can find the other sides using the trigonometric ratios sine, cosine and tangent. Similarly, knowing any two of the sides in a right-angled triangle enables us to find all the angles. Not all triangles contain a right-angle.
