You can put this solution on YOUR website!
in a parallelogram, opposite sides are parallel to each other and they are congruent.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "since AB is opposite CD and AD is opposite BC, you get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3x-5 = x+7 and you get y+3 = 2y-7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get x = 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for y to get y = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3x-5 becomes 18-5 = 13
\n" ); document.write( "x+7 becomes 6+7 = 13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y+3 becomes 10+3 = 13
\n" ); document.write( "2y-7 becomes 20-7 = 13\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "looks like all sides are congruent, therefore your parallelogram is a rhombus.\r
