Answer 1

Answer:

1 = (180-40) = 140 (Reason : Adjacent Angles sum up to 180)

2 = 40  (Reason : Opposite angles are of equal length)

3 = 140  (Reason : Opposite angles are of equal length)

6 = 140 (Reason : Alternate angles are of equal length)

7 = 40 (Reason : Alternate angles are of equal length)

4 = (180-40) = 140 (Reason : Adjacent Angles sum up to 180)

5 = (180-140) = 40 (Reason : Adjacent Angles sum up to 180)
