Question

plz hlp me ABCD is a parallelogram . the circle through A,B and C intersect CD at E. Prove that AE=AD

Answer 1

We know the sum of the opposite angles is 180°.

$∠AEC+∠CBA=180$
$∠AEC+∠AED = 180$ (Linear pair)
$∠AED = ∠CBA$ ... (1)
For a parallelogram, opposite angles are equal.
$∠ADE=∠CBA$... (2)
From (1) and (2)
$∠AED=∠ADE$
$AD=AE$

$∠$ means angle

Answer 2

AD = AE. Its the answer. i just did it with out steps.
