Question

Given the points A(2,1,-2), B(1,3,0), C(4,-1,5), and the origin O:
(a) calculate the volume of the parallelopiped with edges parallel to OA, OB, and OC.
(b) find line equation for the perpendicular bisectors of the line segments AB and BC which lie in the plane ABC.
(c) find the distance of this intersection point from each of the points A, B, and C.

Answer 1

hi

Answer 2

if you take the determinant it will tell you the volume

Answer 3

A B C if they have origin as the starting point u can rewrite as 3 vectors
