Mohit got an assignment where he had to explain the types of angles formed by a pair of parallel lines.
He completed the assignment but when his teacher checked he saw mistakes. Identify the correct option pointing out the mistake in the parts (i to iv).
|Types of Angle||Observations|
|(i) Corresponding||∠ 1 = ∠ 5,
∠ 3 = ∠ 7,
∠ 2 = ∠ 6,
∠ 4 = ∠ 8
|(ii) Alternate interior||∠ 3 = ∠ 6,
∠ 4 = ∠ 5
|(iii) Vertically opposite||∠ 1 = ∠ 4,
∠ 5 = ∠ 6
|(iv) Alternate exterior||∠1 = ∠8,
∠2 = ∠5
A Only (i)
B Only (ii)
C Both (i) and (iii)
D Both (iii) and (iv)
