If $\"B\"$ is the midpoint of $\"MD\"$ , then by defintion,
\n" ); document.write( " $\"MB=BD\"$
\n" ); document.write( "Also,
\n" ); document.write( " $\"MD=MB%2BBD\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"MD=MB%2BMB\"$
\n" ); document.write( " $\"MD=2%2AMB\"$ \n" ); document.write( "

\n" );
