If A,B,C have position vectors (0,1,1), (3,1,5),(0,3,3) respectively,show that Delta ABC is right angled at C.

If A,B,C have position vectors (0,1,1),(3,1,5),(0,3,3) respectively, prove that triangle ABC is right angled at C.

If A,B,C have position vectors (0,1,1)(3,1,5),(0,3,3), respectively,then show that Delta ABC is right angled at C.

If A ,\ B ,\ C have position vectors (0, 1, 1), (3, 1, 5), (0, 3, 3) respectively, show that "Delta"A B C is right angled at Cdot

If A(0,1,1), B(3, 1,5) and C(0, 3, 3) are three points show that DeltaABC is right angled at C.

If the vertices A,B,C of triangle ABC have position vectors (1,2,3), (-1,0,0),(0,1,2) respectively what is the magnitude of the angle ABC?

If the vertices A,B,C of a triangle ABC have position vectors (1,2,3),(-1,0,0)(0,1,2) respectively then find angle ABC (angle ABC is the angle between the factors BA and BC).

If A,B,C have position vectors (2,0,0),(0,1,0),(0,0,2), show that ABC is isosceles.
