A. $\frac{r_1}{r_2}=\frac{1}{2}\backslash frac\{r\_\{1\}\}\{r\_\{2\}\}=\backslash frac\{1\}\{2\}$

B. $\frac{r_1}{r_2}=\frac{\sqrt{2}}{2}\backslash frac\{r\_\{1\}\}\{r\_\{2\}\}=\backslash frac\{\backslash sqrt\{2\}\}\{2\}$

C. $\frac{r_1}{r_2}=\frac{\sqrt{2}}{\sqrt{3}}\backslash frac\{r\_\{1\}\}\{r\_\{2\}\}=\backslash frac\{\backslash sqrt\{2\}\}\{\backslash sqrt\{3\}\}$

D. $\frac{r_1}{r_2}=\frac{\sqrt{3}}{2}\backslash frac\{r\_\{1\}\}\{r\_\{2\}\}=\backslash frac\{\backslash sqrt\{3\}\}\{2\}$
