In the adjoining figure, O is the centre of the circle. AB and CD are equal chords. If `/_AOB =100^(@)`, then find `/_CED`. |

Answer» Equal chords subtend equal angles at the centre of the circle. `/_ AOB=100^(@)` `implies /_DOC =100^(@)` (Angle subtended by an arc at the centre of the circle is twice the angle subtended by it anywhere in the remaining part of the circle ) `:. /_CED =(1)/(2)(100^(@))=50^(@)` |
