Let A = (−3, 2), B = (1, 0), and C = (4, 6). Prove that △ABC is a right-angled triangle. Let u = AB, v = BC, and w = AC. We must show that u · v, u · w, or v · w is zero in order to show that one of these pairs is orthogonal. u · v =
u · w =
v · w =
Since , △ABC is a right-angled triangle.
A. AB ⊥ BC
B. BC ⊥ AC
C. AB ⊥ AC

Which statements about these triangles is true
