Answer:
3. ∠A = 110°
4. ∠H = 70°
5. ∠D = 70°
6. ∠F = 70°
Explanation:
In a parallelogram, adjacent angles are supplementary (sum to 180°).
⇒ ∠A + ∠B = 180°
⇒ ∠A + 70° = 180°
⇒ ∠A = 110°
In a parallelogram, opposite angles are congruent.
⇒ ∠C = ∠A = 110°
⇒ ∠D = ∠B = 70°
If two parallelograms are similar, their corresponding interior angles are congruent.
⇒ ∠A = ∠E = 110°
⇒ ∠B = ∠F = 70°
⇒ ∠C = ∠G = 110°
⇒ ∠D = ∠H = 70°
