    It is called the HINGE theorem, because...

    the vertex of the angle acts like a hinge to open the triangle.

    it's named after Joseph Hinge, the man who discovered it.

    "hinge" is the Spanish word for angle.

    the triangle makes a hinge shape, like a tent.

    Compare mACD and mGDEm\angle ACD\ and\ m\angle GDE

    mACB > mGDEm\angle ACB\ >\ m\angle GDE

    mACD < mGDEm\angle ACD\ <\ m\angle GDE

    mACB = mGDEm\angle ACB\ =\ m\angle GDE

    ACB GDE\angle ACB\ \cong\ \angle GDE
