Introduction to Trigonometry  Math is Fun
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 (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  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.
Unit 4: Trigonometric equations and identities  Khan Academy
In this unit, you'll explore the power and beauty of trigonometric equations and identities, which allow you to express and relate different aspects of triangles, circles, and waves.
Trigonometry  Algebra 2  Math  Khan Academy
Let's extend trigonometric ratios sine, cosine, and tangent into functions that are defined for all real numbers. You might be surprised at how we can use the behavior of those functions to model realworld situations involving carnival rides and planetary distances.
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.

Trigonometry  Brilliant Math & Science Wiki
Trigonometry concerns the description of angles and their related sides, particularly in triangles. While of great use in both Euclidean and analytic geometry, the domain of the trigonometric functions can also be extended to all real and complex numbers, where they become useful in differential equations and complex analysis.
