An example of a tangent and radius of a circle showing how they touch the circumference of the circle and are at right angles to each other

 

Example 2

The straight blue line is a tangent to the red curved line on this graph

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

 

Example 3

The straight blue line is a tangent to the red curved line on this graph it touches the curve at point a
