triangle ABC is an isosceles triangle, with AB=AC.If CE is drawn parallel to AB such that AE bisect exterior<CAD . prove that (a) <DAE=<ABC (b)ABCE is a parallelogram.
if a trangle is ABC is a isosceles traingle . AC = AB . so BC is not equal to AC and AB . if angle AE biscest exterior and EC will be join as well . so it will form a parallelogram
the answer of set b
