Trigonometry  Wikipedia
Trigonometry. 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.

Trigonometry helps us find angles and distances, and is used a lot in science, engineering, video games, and more! RightAngled Triangle. The triangle of most interest is the rightangled triangle. The right angle is shown by the little box in the corner: Another angle is often labeled θ, and the three sides are then called:

Trigonometry  Definition, Formulas, Ratios, & Identities
Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.He considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or surface, as shown by the inscribed triangle ABC in ...
