What is Trigonometry ?
Answers
Answer:
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
These are just some extra knowledge-
The angles are either measured in radians or degrees. The commonly used trigonometry angles are 0°, 30°, 45°, 60° and 90°.

Sin θ y/1 = y
Cos θ x/1 = x
Tan θ y/x
Basic Trigonometric Function Formulas
By using a right-angled triangle as a reference, the trigonometric functions or identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.

Step-by-step explanation:
Trigonometry is one of those divisions in mathematics that helps in finding the angles and missing sides of a triangle with the help of trigonometric ratios. The angles are either measured in radians or degrees. The commonly used trigonometry angles are 0°, 30°, 45°, 60° and 90°.
