A symbol/notation for a line tangent to something?

369 Views Asked by At

I was doing problems of analytical geometry, specifically things like: "Find the equation of the circumference given the line tangent to it of equation...". I was wondering, since there is a way to write down that a line is parallel to another with pure mathematical notation, is there any way that mathematicians do the same for lines tangent to another line, a parabola, a circumference, etc? That is, is there some form of notation or symbol for that?
