The two adjacent angles of a kite are given to be 60° and 100°. The other two angles could be

Case I:

We know that the opposite angles corresponding to the bigger diagonal are equal.
∴ The other two angles could be 100° and (360−60−100−100)° i.e. 100°

Case II:

We know that the opposite angles corresponding to the bigger diagonal are equal.
∴ The other two angles could be 60° and (360−60−60−100)° i.e. 140°
