Q.7 plss.....urgent Share with your friends Share 0 Lovina Kansal answered this Dear student Here ∠AEO and ∠DEO are equal ( vertically opposite angle) Join OA and OC, So in△OAE and △OCE, we have OA = OC ( radius ) OE is common in both And ∠OAE =∠OCE=90° So Both are congruent triangle So ∠AEO and ∠CEO are equal. Similarly for other circle ∠DEO = ∠BEO As AEO and DEO are equal So all four angle are equal and bisected by OE and EO' Hence O ,E' and O are collinear. Regards 1 View Full Answer
