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.
