A tangent line curve, or surface; specifically, that portion of the straight line tangent to a curve that is between the point of tangency and a given line, the given line being, for example, the axis of abscissas, or a radius of a circle produced. See Trigonometrical function, under Function.

Touching; touching at a single point

meeting a curve or surface at a point and having at that point the same direction as the curve or surface; -- said of a straight line, curve, or surface; as, a line tangent to a curve; a curve tangent to a surface; tangent surfaces.

A line in the "direction" of the surface at the intersection point. Mathematically, the tangent is a straight line with a slope equal to the slope of the surface at the point of intersection. In the image to the right, the blue line is the tangent to the black surface at the red point of intersection. Check out this link to MathWorld for more information.

The direction of a curve; also, specified point; also, a line through this point and oriented in this direction.

Making contact at a single point or along a line; touching but not intersecting.

(4) Intersecting at exactly one point.

Straight sections of trackage.

a straight line or plane that touches a curve or curved surface at a point but does not intersect it at that point

a line , curve , or surface , touching but not intersecting another line, curve, or surface

a line intersecting a circle exactly once

a line that touches a circle at only one point without intersecting it

a line which lies in the plane of the circle and intersects the circle in exactly one point

a line which touches a circle at one point (called the point of tangency) only

a straight line drawn at any point on the circumference of a circle touching but not cutting the curve

a straight line touching a circle at one point only

a straight line which touches the curve at one point only

Intersecting a circle at exactly one point. For general curves, tangents intersect the curve at one point near that point.

A mathematical term used in the construction of some geometric map projections describing a straight line or plane surface touching a curved line or curved surface at a single point but not intersecting it.

A line that intersects a curve at a single point along the surface.

Straight section of material on either side of the bend or arc. May be any length. Notes: In order to make the bend itself, there has to be sufficient material at each end during the bending process. Excess may be trimmed after.

line or segment which intersects a curve in only one point. In both examples below line is tangent to the curve. Even though the second illustration shows the line intersecting the curve in more than 1 point, "locally" around point P, there is only one point of intersection. This is a special relationship because a line could easily intersect a curve iin zero or two points. Tangency is special with the touching at only one point.

(1) a line which touches or intersects a curve at one point in the immediate vicinity of the point (in the case of a circle, it touches the curve only once); (2) a trigonometric ratio defined, in terms of a right triangle, as the length of the opposite side divided by the length of the adjacent side ( w.r.t. a specified angle)

a straight line that touches a curve at a single point and does not cross through it

The beginning and ending of an arc or bend.

A line that touches a curve at only one point (the point of tangency).

The condition created when two elements nearly touch, touch, or overlap with each other. (See samples.)

1. A straight line that touches a curve at one point but continues on without crossing it. 2. The trigonometric ratio of the sides opposite and adjacent to an angle in a right-angled triangle.

Straight portion after a curve conveyor.

In general, a line or vector that indicates the slope of a curve at a given point.

A tangent is a line segment, line, or ray that intersects a circle in only one point.

(n) A condition in which a straight line is in contact with a curve at only one point. Tangents describe the smooth transition from a linear/planar element to a curved one. Geometric construction techniques are used to define tangent curves in an engineering drawing.
