Answer: c Explanation: Given, AB = BC Hence, ∠A=∠C And ∠B = 70 ° By angle sum property of triangle we know: ∠A+∠B+∠C = 180 ° 2∠A+∠B=180 ° 2∠A = 180-∠B = 180-70 = 110 ° ∠A = 55 ° 2) For two triangles, if two angles and the included side of one triangle are equal to two angles and the included side of another triangle. Then the congruency rule is: a.

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).
