Solution: As per given in the question, ∠DAB = ∠CBA and AD = BC. (i) ΔABD and ΔBAC are similar by SAS congruency as AB = BA (common arm) ∠DAB = ∠CBA and AD = BC (given) So, triangles ABD and BAC are similar i.e. ΔABD ≅ ΔBAC. (Hence proved). (ii) As it is already proved, ΔABD ≅ ΔBAC So, BD = AC (by CPCT) (iii) Since ΔABD ≅ ΔBAC So, the angles,

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).
