Points (3,1) and (8,1) are on the horizontal line with y=1, 8-3=5 units apart.
\n" ); document.write( "Points (6,5) and (k,5) are on the horizontal line with y=5, parallel to y=1.
\n" ); document.write( "In a parallelogram, sides that are parallel are congruent,
\n" ); document.write( "so the distance between (6,5) and (k,5) must also be 5.
\n" ); document.write( "Either k=6+5=11, or k=6-5=\"highlight%281%29\" .
\n" ); document.write( " or
