Line Intersection is a point where two or more lines intersect each other. If you want to calculate the line intersection coordinates without using any software or app then check out these websites. All of these websites are completely free to use and can be accessed from anywhere....
By applying Helly’s Theorem, we prove that it is sufficient to examine the intersection of all subsystems consisting of 𝑑+1 disks to determine if the system has a nonempty intersection. In Section 3, we define Vietoris–Rips systems and Čech systems, together with presenting results ...
