Pair of congruent triangles and incomplete statements related to them are given below. Observe the figures carefully and fill up the blanks:
(a) In the adjoining figure if ∠C = ∠F, then AB = ---------- and BC = ----------.
(b) In the adjoining figure if BC = EF, then ∠C = --------- and ∠A = ----------.
(c) In the adjoining figure, if AC = CE and ΔABC ≅ ΔDEC, then ∠D = -------- and ∠A = ---------.
