WebTrigonometry relies on the conservation of ratios between corresponding sides of similar right-angled triangles. Consider the case of two similar right-angled triangles. (3, 4, 5) and (6, 8, 10) are Pythagorean triples since 3 2 + 4 2 = 5 2 and 6 2 + 8 2 = 10 2. Therefore, the triangles are right-angled. WebExample 1: find a side given the angle and the hypotenuse. ABC is a right angle triangle. The size of angle ACB = 60º and the length BC = 16cm. Calculate the value of x. Labelling the sides OAH in relation to the angle 60º, we can use the hypotenuse, and we need to find the adjacent side. We therefore need to use the cosine function.
