\n" ); document.write( "Use the following theorems:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Theorem 1: A quadrilateral is a parallelogram if and only if the diagonals bisect each other.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Theorem 2: Vertical angles are congruent\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "===========================================================================\r

\n" ); document.write( "\n" ); document.write( "K bisects EG by Theorem 1.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "EK is congruent to KG by definition of bisector\r
