WebAlso, it's usually defined in terms of current, not voltage. A typical definition of saturation is when \$\beta < 10\$ (or 20, or some other value). So to prove the BJT is in forward-active, you'd need to work out the base and collector currents, and show their ratio is above the threshold you've chosen to define saturation.
