let s be the side of the given isosceles right triangle, then
\n" ); document.write( "s^2 + s^2 = h^2
\n" ); document.write( "2s^2 = h^2
\n" ); document.write( "s^2 = h^2/ 2
\n" ); document.write( "***************************************************************
\n" ); document.write( "Area of triangle = (1/2) * s * s
\n" ); document.write( "Area of triangle = (1/2) * s^2
\n" ); document.write( "Area of triangle = (1/2) * (h^2/2) = (h^2 / 4)\r
\n" ); document.write( "
