Question

ABCD is a quadrilateral in which AD = BC and ∠ DAB = ∠ CBA . Prove that ∆ ABD ≅ ∆ BAC​

Answer 1

Step-by-step explanation:

AD = BC............given

angle DAB = angle CBA..............given

now in triangle ABD and BAC

side AD = side BC ............given

<DAB = <CBA............given

side AB = side BA ..............common side

therefore, triangle
