it goes something like this
\n" ); document.write( ":
\n" ); document.write( "given AC is congruent to BD
\n" ); document.write( ":
\n" ); document.write( "AC=AB+BC
\n" ); document.write( "BC=CD+BC
\n" ); document.write( ":
\n" ); document.write( "by subtraction property subtracting out BC from these you have
\n" ); document.write( ":
\n" ); document.write( "AB=CD
\n" ); document.write( "
\n" );
