Solution: (b) We know that, if ΔRST is congruent to ΔUVW i.e., ΔRST = ΔUVW, then sides of ΔRST fall on corresponding equal sides of ΔUVW and angles of ΔRST fall on corresponding equal angles of ΔUVW. Here, given AB = QR, BC = PR and CA = PQ, which shows that AB covers QR, BC covers PR and CA covers PQ i.e.,

Solution: In quadrilateral ACBD, we have AC = AD and AB being the bisector of ∠A. Now, In ∆ABC and ∆ABD, AC = AD (Given) ∠ CAB = ∠ DAB ( AB bisects ∠ CAB) and AB = AB (Common) ∴ ∆ ABC ≅ ∆ABD (By SAS congruence axiom) ∴ BC = BD (By CPCT) Ex 7.1 Class 9 Maths Question 2. ABCD is a quadrilateral in which AD = BC and ∠ DAB = ∠ CBA (see figure).
