Trigonometry  Wikipedia
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') [1] is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.

What is Trigonometry? Trigonometry is one of the most important branches in mathematics that finds huge application in diverse fields. The branch called “Trigonometry” basically deals with the study of the relationship between the sides and angles of the rightangle triangle.
Trigonometry  from Wolfram MathWorld
Trigonometry. The study of angles and of the angular relationships of planar and threedimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions ) comprising trigonometry are the cosecant , cosine , cotangent , secant , sine , and tangent .

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a RightAngled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: "Opposite" is opposite to the angle θ "Adjacent" is adjacent to (next to) the angle θ "Hypotenuse" is the long one
