Question

Point $D$ has coordinates as $(3,4,5)$. Referring to the given figure, find the coordinates of point $C$.

• A. $(4,0,0)$
• B. $(0,3,4)$
• C. $(0,3,0)$
• D. $(0,4,0)$

Answer 1

The correct option is D $(0,4,0)$

It is given that $D=(3,4,5)$. Then, obviously, $E=(0,4,5)$. Since the point C lies on y axis, hence the corresponding point C will be (from the coordinates of E we found earlier ) $C=(0,4,0)$.
