Answer 1

Answer:

Given, AD = BC and angle DAB = angel CBA.

prove that : (I) triangle ABD = triangle BAC

(II) BD = AC

(III) angle ABD = angle BAC

proof : (I) In triangle ABD and BAC ,

AD = BC ( Given ) ................(side)

angle DAB = angle CBA ( Given ).........(angle)

AB = CD ( Parallel to each other ) ......(side)

By SAS criteria :

triangle ABD congruent to triangle BAC.

(II) Therefore, BD = AC ( CPCT).

(III) ALSO , angle ABD = angle BAC ( CPCT ).
