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.

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 is the study of the relationships between the sides and angles of right triangles. The legs are called adjacent or opposite depending on which acute angle is being used.
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.
