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.
