Question

RIANGLES
2. ABCD is a quadrilateral in which AD = BC and
Z DAB = Z CBA (see Fig. 7.17). Prove that
(1) ABD = BAC
(ii) BD=AC
(iii) ABD = BAC.​

Answer 1

Step-by-step explanation:

in triangle abd and bac

ad = bc (given)

angle dab = angle cba (Given)

ab = ba

So Triangle ABD is Congruent To BAC (SAS congruency )

BD = AC (cpct)

angke abd = angle bac (cpct)
