For \\(\triangle ABC\\), the following propositions are given:  
\\(①\\) If \\(\dfrac{\tan A}{\tan B} = \dfrac{a^{2}}{b^{2}}\\), then \\(\triangle ABC\\) must be an isosceles triangle;  
\\(②\\) If \\(\dfrac{b^{2} + c^{2} - a^{2}}{a^{2} + c^{2} - b^{2}} = \dfrac{b^{2}}{a^{2}}\\), then \\(\triangle ABC\\) must be an isosceles triangle;  
\\(③\\) If \\(\sin^{2}A + \cos^{2}B = 1\\), then \\(\triangle ABC\\) must be an isosceles triangle;  
\\(④\\) If \\(\sin^{2}A + \sin^{2}B + \cos^{2}C < 1\\), then \\(\triangle ABC\\) must be an obtuse triangle.  
Among these, the incorrect propositions are \_\_\_\_\_\_.
