Abstract：This paper is intended to explore the max area of a triangle of ellipse by useing The Ge‐ometer's Sketchpad tool .It gives a triangle which is made of origin of coordinates and the point P and Q , which are the point of intersection by a line l and a ellipse .The line l passed one point A which is on the coordinate axis .It proves the max of the triangle is a immovable figure which is related to the semi‐major axis and the semi‐minor axis of the ellipse when the longth of OA is big than a figure .
