Answer 1

Step-by-step explanation:

We know, If a transversal intersects two lines such that a pair of alternate interior angles are equal, then the two lines are parallel From figure: ∠EDC = ∠DCA = 100° Lines DE and AC are intersected by a transversal DC such that the pair of alternate angles are equal. So, DE || AC.
