Post by: Alexle101 on August 24, 2014, 10:54:02 pm

The coordinates of three points are A(1,0,5) B(-1,2,4) C(3,5,2)
A) express the vector AB in the form xi + yj + zk (got this)
B) find the coordinates of the point D such that ABCD is a parallelogram (dont get)
C) prove that ABCD is a rectangle (dont get)

Any help would be appreciated :)
