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.
