tan A = (sin A) / (cos A)

tan (A)= opposite side length/adjacent side length

A is an angle measurement; amount of degrees or radians.

If a line is tangent to a curve, it only touches the curve at one point. looks like )| but the line is touching the curve.

In a circle, the tangent line touches the circle at one point and is perpinducular to the circle's radius if it is touching that same point.

What is a tangent line with respect to a circle?

A tangent to a circle is a line which touches the circle once. That is, it does not pass through the circle, which would mean intersecting it twice. A way to form a tangent is draw any line from the centre point of a circle to its edge. A line on the edge perpendicular (at 90 degrees to) this line will be a tangent.
