two vertex of triangle are (1,-5) and (5,1) median intersect at (1, -1)
\n" ); document.write( "let third vertex of triangle is (x,y)
\n" ); document.write( "mid point side (1,-5) and (5,1) where median meet is 5+1/2=3 and -5+1/2=-2
\n" ); document.write( "medians of triangle intersect at the ratio of 2:1
\n" ); document.write( "by using section formula
\n" ); document.write( "we can say 1= 2 multiplied 3+x/3
\n" ); document.write( " 3=6+x
\n" ); document.write( "x=-3
\n" ); document.write( "similarly
\n" ); document.write( "-1=-2 multiplied -2+y/3
\n" ); document.write( "-3=-4+y
\n" ); document.write( "y=1
\n" ); document.write( " third vertex will be (-3,1)
\n" ); document.write( "answer (-3,1)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
