tangent of circle
The tangent of may be defined by using whatever of the below three characterisations.
The is a line
-
•
whose distance

from the centre of the circle is equal to the radius of the circle;
-
•
that is perpendicular
to a radius of the circle and passes through the end point
of the radius lying on the circumference

;
-
•
that has only one common point with the curve.
Note. The tangent of ellipse may also be defined by using the third characterisation.
