Angle ABC = Angle ACD = Angle ADE

Angle BAC = Angle CAD = Angle DAE

Angle ACB = Angle ADC = Angle AED

I don't see how you can fit together triangles

ABC and ACD to form a parallelogram.

Angle BAD would be 60 degrees and

angle BCD would be 150 degrees.

Those two angles would have to be equal

for ABCD to form a parallelogram.
