**Trigonometry** (from the Greek *trigonon* = three angles and *metro* = measure) is a branch of mathematics dealing with angles, triangles and **trigonometric functions** such as **sine**, **cosine** and **tangent**. It has some relationship to geometry, though there is disagreement on exactly what that relationship is; for some, trigonometry is just a subtopic of geometry.
