How to find if circle intersects with triangle in C?

Question

Help? User input three coordinates for a triangle(x, y) and coordinates of center of a circle(x0, y0) and circle radius, program output should be "Yes" if circle intersects triangle or "No" if not.

Answer 1

I think you need to consider the equation for the circumference described by the certer and the radius. Then you have to compare it with the equations of the lines that make the triangle. If you find that equatOfCircle = equatOfOneSide for a point in the plan, then the triangle intersects the circle.
Post an attempt for more support.

Answer 2

The question is unclear. Explain more and show your attempt.

Answer 3

I only did the input, i dont have idea which formula to use to see if circle intersects triangle. What program is supposed to do is in description.
