In Fig. 17.31, ABCD is a parallelogram, CE bisects C andAF bisects A. In each of the following, if the statement is true, give a reason for the same.


(i) A = C


True,


C =A = 55° [In a parallelogram opposite angles are equal]


(ii) FAB=A


True,


AF is the angle bisectoe of angle A


(iii) DCE=C


True,


CE is the angle bisectoe of angle A


(iv) CEB= FAB


True,


C = A [In a parallelogram opposite angles are equal]


[AF and CE are angle bisectors]


(v) CE || AF


True, Since one pair of opposite angles are equal, therefore Quad AEFC is aparallelogram.
