In the given figure, find out the number of angles formed within the arms OA and OE.
In the given figure, the angles within the arms OA and OE are as follows:
(i) ∠AOE
(ii) ∠AOD
(iii) ∠AOC
(iv) ∠AOB
(v) ∠BOC
(vi) ∠BOD
(vii) ∠BOE
(viii) ∠COD
(ix) ∠COE
(x) ∠DOE
Therefore, the number of angles will be 10.
