Trigonometry  Wikipedia
Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle' and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and side lengths of triangles.
Introduction to Trigonometry  Math is Fun
The main functions in trigonometry are Sine, Cosine and Tangent. They are simply one side of a rightangled triangle divided by another. For any angle "θ": (Sine, Cosine and Tangent are often abbreviated to sin, cos and tan.)

Trigonometry  Definition, Formulas, Ratios, & Identities
Trigonometry, the branch of mathematics concerned with specific functions of angles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Learn more about trigonometry in this article.
Trigonometry  What is Trigonometry? Formulas, Table, Examples  Cuemath
Trigonometry is the branch of mathematics that deals with the relationship between ratios of the sides of a rightangled triangle with its angles. The ratios used to study this relationship are called trigonometric ratios, namely, sine, cosine, tangent, cotangent, secant, cosecant.
Sine, Cosine, Tangent  Math is Fun
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.
Trigonometry  Math.net
Trigonometry (named based on a Greek word that loosely translates to "measurement of triangles") is a branch of mathematics that studies the relationships between the sides and angles of triangles. Trigonometry has many practical applications and is used in astronomy, surveying, navigation, and more.

Not only are right triangles cool in their own right (pun intended), they are the basis of very important ideas in analytic geometry (the distance between two points in space) and trigonometry.
