Question

in the given figure,AB & AC are 2 chords of a circle whose center is O . If OD perpendicular AB, OE perpendicular AC & AO bisects angle DAE, prove that ∆ADE is an issosceles ∆ & angle ABC = angle ABC
​

Answer 1

angle ABC = angle ABC

hence proved that ∆ADE is an issosceles ∆ & angle ABC = angle ABC
