: the trigonometric function that for an acute angle is the ratio between the leg opposite to the angle when it is considered part of a right triangle and the leg adjacent.

Tangent - Wikipedia
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is, intuitively, the straight line that "just touches" the curve at that point.
Sine, Cosine and Tangent - Math is Fun
Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of a right triangle: Opposite is always opposite the angle. And Adjacent is always next to the angle.
Tangent | Definition, Formulas, & Facts | Britannica
tangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is tan A = length of side opposite angle A/ length of side adjacent to angle A. The other five trigonometric functions are sine (sin), cosine (cos), secant (sec), cosecant (csc), and cotangent (cot).
Tangent Meaning in Geometry and Trigonometry - BYJU'S
In Geometry, the tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In other words, it is defined as the line which represents the slope of a curve at that point.
Tangent - definition of tangent by The Free Dictionary
off on or at a tangent, digressing suddenly from one course of action or thought and turning to another.
Tangent – Explanation & Examples - The Story of Mathematics
In the context of a triangle, the tangent function is the ratio of the opposite side to the adjacent side. For an angle α, the tangent function is denoted by tan α. In other words, the tangent is a trigonometric function of any given angle. The following figure 5-1 represents a typical right triangle.
Tangent -- from Wolfram MathWorld
The common schoolbook definition of the tangent of an angle in a right triangle (which is equivalent to the definition just given) is as the ratio of the side lengths opposite to the angle and adjacent the angle, i.e.,
TANGENT definition and meaning | Collins English Dictionary
Was he on a tangent, trying to relive an exciting part of his life? But why, she wondered, her thoughts leaping off at a tangent, had that balding, thick-set man seemed familiar? He walked crookedly, either bumping into me or wandering away at a tangent.
