A Tangent is a line that touches a curve at one point without cutting across it.

A tangent is a straight line that touches a curve at right angles

Tanned when she gently (tangent) touched the circle.                                                                                                                                                                                                                                                                      

Example 1

The tangent touches the circle at one point – a tangent.

A tangent touches the curve and the radius meets it at a right angle


Example 2

The tangent here is still going through a curve making it a tangent it doesn’t have to be a circle

Although the red line is curved in several ways, the blue line is still a tangent to the red line.


Example 3

This tangent is meeting the curve so it is a tangent, the meeting point can be anywhere on the curve

The tangent meets the line on the graph at point a.
