ANSWER:

1. If m∠ 2 = 70°, then m∠ 6 = 70°

2. If m∠ 2 = 70°, then m∠ 7= 70°

3. If m∠ 8 = 110°, then m∠ 1= 110°

4. If m∠ 7 = 70°, then m∠ 4= 110°

5. If m∠ 6 = 70°, then m∠ 1= 110°

EXPLANATION:

m∠1 and m∠2 = 180°

m∠3 and m∠4 = 180°

m∠5 and m∠6 = 180°

m∠7 and m∠8 = 180°

Therefore;

m∠1 = m∠4 = m∠5 = m∠8 = 110°

m∠2 = m∠3 = m∠6 = m∠7 = 70°
