You can put this solution on YOUR website!
I would say you have your work cut out for yourself.
\n" ); document.write( "Any line connecting the midpoints is parallel to a side of the original triangle
\n" ); document.write( "Pick two of the points.
\n" ); document.write( "Find the line that goes through them.
\n" ); document.write( "Get the slope
\n" ); document.write( "Plug in an the x,y.
\n" ); document.write( "Use the same slope. Get the line.
\n" ); document.write( "Do it two more times.
\n" ); document.write( "Find where those lines intersect.
\n" ); document.write( "The intersections will be the vertices.
\n" ); document.write( " \r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
