(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given that P,Q and R lie on the hyperbola xy=c^{2}, prove that if PQ and PR inclined equally to the coordinate axes, then QR passes through O.

2. Relevant equations

3. The attempt at a solution

I don't understand what does ''PQ and PR are inclined equally to the coordinate axes'' means.. can anyone explain?
