$$\text{You can't use 'macro parameter character \#' in math mode}$$$$\mathbf{a}\mathrm{always}\mathrm{moves}\mathrm{towards}{\mathbf{b}}^{\prime }\left(insteadof\mathbf{b}\right),$$$$\mathbf{b}\mathrm{always}\mathrm{moves}\mathrm{towards}{\mathbf{c}}^{\prime }\left(insteadof\mathbf{c}\right),$$$$\mathbf{c}\mathrm{always}\mathrm{moves}\mathrm{towards}{\mathbf{d}}^{\prime }\left(insteadof\mathbf{d}\right),$$$$\mathbf{d}\mathrm{always}\mathrm{moves}\mathrm{towards}{\mathbf{a}}^{\prime }\left(insteadof\mathbf{a}\right),$$$$\mathrm{where}{\mathbf{a}}^{\prime },{\mathbf{b}}^{\prime },{\mathbf{c}}^{\prime }\mathrm{and}{\mathbf{d}}^{\prime }\mathrm{are}\mathrm{midpoints}\mathrm{of}\mathrm{line}$$$$\mathrm{segments}\mathbf{ab},\mathbf{bc},\mathbf{cd}\mathrm{and}\mathbf{da}\mathrm{respectively}.$$

$$\mathrm{Whatif}{\mathbf{b}}^{\prime }\mathrm{is}\mathrm{on}\overleftrightarrow{\mathbf{bc}}\mathrm{beyond}\mathrm{the}\mathbf{b},$$$${\mathbf{c}}^{\prime }\mathrm{is}\mathrm{on}\overleftrightarrow{\mathbf{cd}}\mathrm{beyond}\mathrm{thd}\mathbf{c}\dots \mathrm{for}\mathrm{example}$$$$\mathrm{when}{\mathbf{bb}}^{\prime }=\mathbf{bc},{\mathbf{cc}}^{\prime }=\mathbf{cd}\dots .$$
