When a transversal cuts two parallel lines, the number of pairs of corresponding angles formed are ______.

• A.
  5
• B.
  4
• C.
  3
• D.
  2

Answer 1

The correct option is B

4
From the figure, the pair of corresponding angles are:
(i) ∠1 and ∠5
(ii) ∠2 and ∠6
(iii) ∠3 and ∠7
(iv) ∠4 and ∠8
Therefore, when a transversal cuts two parallel lines, then number of pairs of corresponding angles formed are 4.
