Trigonometry is a branch of mathematics that means "measurement of, with and by means of triangles".

Astronomers as early as 150 BC developed the study of trigonometry. By about 1500 AD the trig. ratios (sine, cosine and tangent) were established. Once again, right-angled triangles, as in Pythagoras' Theorem, are important when making calculations with the trig ratios.

Rule relating the lengths of the sides of a right triangle. It says that the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse (the side opposite the right angle). That is, a² + b² = c², where c is the length of the hypotenuse. Triads of whole numbers that satisfy it (e.g., 3, 4, and 5) are called Pythagorean triples
