Answer» Let $c_{1} & c_{2}$ be the centers and $r_{1} & r_{2}$ be the radius of two circles. Then Cases Conditions p. 1. $\| r_{1} - r_{2} \| < c_{1} c_{2} < r_{1} + r_{2}$ q. 2. $\| r_{1} - r_{2} \| = c_{1} c_{2}$ r. 3. $c_{1} c_{2} < \| r_{1} + r_{2} \|$ s. 4. $r_{1} + r_{2} < c_{1} r_{2}$ t. 5. $r_{1} + r_{2} = c_{1} r_{2}$
