Hello! I was wondering how I would calculate the intersection of two lines in a program. So far I have a program where you put in three coordinates for a triangle that is inscribed in a circle, and then I solve for two lines that will intersect at the middle of the circle, it then graphs the lines and the triangle, but then to find the center of the circle, you need to puse 2nd, Trace, 5. I would like it to be where you put in the three cords, and it finds the intersect for you, does anyone know how to do this? Thanks!
