# Proving a 2:1 ratio triangle having a Zero Vector

## Homework Statement

I need help once again with this question below:

Thanks,

## The Attempt at a Solution

This is what I have so far:
GP = GQ + QP
GQ = GP + PQ
GR = GP + PR

GP + GQ + GR = GQ + QP[-] + PQ[+] + GP + PR + GP
GP + GQ + GR = GQ + 2GP + PR

I am stuck now. I took the approach of taking GP + GQ + GR individually and finding their vector components.
