circle

Question: The equation of a circle touching the axes of coordinates and the line $x\cos \alpha +y\sin \alpha =2$ can be

1) ${{x}^{2}}+{{y}^{2}}-2gx-2gy+{{g}^{2}}=0$, where $g=\frac{2}{(\cos \alpha +\sin \alpha +1)}$

2) ${{x}^{2}}+{{y}^{2}}-2gx-2gy+{{g}^{2}}=0$, where $g=\frac{2}{(\cos \alpha +\sin \alpha -1)}$

3) ${{x}^{2}}+{{y}^{2}}-2gx+2gy+{{g}^{2}}=0$, where $g=\frac{2}{(\cos \alpha -\sin \alpha +1)}$

4) All of these
