The problem seems to come down to special cases of SSA.
When you speak about 'diagonals' there is am implication that these are longer than the missing third side, and that the 'diagonals' cross while the missing third sides do not cross.
If this is true, then you are in a subcase where SSA gives the necessary congruence.

Poor phrasing up there, let me try again:
Is it true that IF a quadrilateral has two equal base angles and diagonals of equal length, it must be an isosceles trapezoid? If so, etc, etc...
