algorithm - C Program to detect right angled triangles - if given 100 points in coordinate system, , have find if there exist right angled triangle in vertices. there way can observe right angled triangle among vertices without having take pairs of 3 vertices , applying pythagoras theorem on them?? can there improve algorithm this? help. :) here's o(n^2 log n)-time algorithm two dimensions only. i'll describe goes wrong in higher dimensions. let s set of points, have integer coordinates. each point o in s, build set of nonzero vectors v(o) = {p - o | p in s - {o}} , test whether v(o) contains 2 orthogonal vectors in linear time follows. method 1: canonize each vector (x, y) (x/gcd(x, y), y/gcd(x, y)), |gcd(x, y)| largest integer divides both x , y, , gcd(x, y) negative if y negative, positive if y positive, , |x| if y zero. (this similar putting fraction in lowest terms.) key fact 2 dimensions that, each nonzero vector, there exists 1 canonical vector orthog...
