How to draw the tangent point from a point to a circle
How to draw the tangent point from a point to a circle?
There are two tangent points from a exterior point to a circle. It is important to say which point you want to draw.
There are two ways of indicating which of the two points you want to draw:
1) Look from the point towards the circle. One of the tangent points is on the left and the other is on the right. You can indicate the left tangent point or the right tangent point.
2)Use another additional point. You can indicate the tangent point that is near the additional point or the tangent point that is far of the additional point.
