Does measuring one photon preserve entanglement with the other?

[Ryan Reed]

When two photons' spins are entangled, measuring one spin gives you the spin of the other. My question is, after one of the particles is measured, does it still retain its entanglement? Could you keep measuring photon A's spin to get photon B's spin?

No. You get at most one measurement on each particle.
