I have a coordinate proof problem with isoceles trapezoid. It is on a coordinate plane with the longest side facing up. the bottom leftcorner is S with points of(a,0) the bottom right is T with points of (b,0) The top RIGHT is W (?,c) The top LEFT is touching the y axis and is Y with (?,?)Find the question marks. P.S. the S and T Points are also touching the x axis HELP!!! PLEASE!!!  </SPAN>\n" );
