    In the adjoining figure if\[m\angle AB=m\angle ACE\], then\[\Delta ABC\]is:

    A)  right-angled                  

    B)  Isosceles  

    C)  equilateral        

    D)         obtuse-angled

    Correct Answer: B

    Solution :

     Since\[\angle ABD=\angle ACE\] \[\therefore \]      \[{{180}^{o}}-\angle ABC={{180}^{o}}-\angle ACB\] \[\Rightarrow \]   \[\angle ABC=\angle ACB\] Hence, \[\Delta ABC\] is isosceles triangle
