Let A = (-2, 9), B = (1, 0), and C = (7, 2). Prove that AABC is a right-angled triangle. Let u = AB, v = BC, and w = AC. We must show that u. v, uw, or vw is zero in order to show that one of these pairs is orthogonal. U V = U. W = V.W = Based on your previous answers, it can be concluded that AABC is a right-angled triangle because of which of the following? O AB L BC O BC LAC O AB LAC
