Answer 1

Explain ur question correctly

Answer 2

Since AE bisects angle DAB then angle DEA is congruent to angle DAE and that makes triangle DAE an equiangular triangle

Step-by-step explanation:

Since triangle DAE is equiangular, it also makes it equilateral. We know AD = BC because opposite sides of a parallelogram are equal and AD = DE because they are sides of an equilateral triangle.

Hence that makes BC = DE
