    Given a chord AB in a circle as shown. If two more chords AD and BE are drawn perpendicular to AB then

    A)  \[\angle S\]                 

    B)  \[{{98}^{o}}\]

    C)  \[{{108}^{o}}\]                  

    D) None of these

    Correct Answer: A

    Solution :

    Join BD and AE as shown in the diagram. Since, \[\Rightarrow \] as shown in the figure, DAB and DEB must be semi-circles and AE = BD are diametres. By RHS congruency, both triangles ADB and AEB are congruent. Hence, BE = AD.
