A right triangle is inscribed in a rectangle \(ABCD\) such that one vertex of the triangle is at \(A\) and the other two vertices lie on the sides \(BC\) and \(CD\) respectively. Let \(T_1\), \(T_2\), and \(T_3\) be the areas of the three right triangles formed, where \(T_1\) is the area of the triangle with the hypote...
