Your Answer
A

 a – iv, b – ii, c – iii, d - i

Correct Answer
B

 a – iv, b – iii, c – i, d - ii

Your Answer
C

 a – iii, b – iv, c – i, d - ii

Your Answer
D

 a – iii, b – iv, c – ii, d - i


Solution

The correct option is A

 a – iv, b – iii, c – i, d - ii


I. Corresponding angles: the angles which occupy the same relative position at each intersection are called corresponding angles. If the two lines are parallel, the corresponding angles are equal. In the above case, the corresponding angles are 1 – 5, 2 – 6, 3 – 7 and 4 – 8.

II. Alternate exterior angles: thepairs of angleson opposite sides of the transversal, but outside the two lines, are called alternate exterior angles. If  the two lines are parallel, the alternate exterior angles are equal. Here, the alternate exterior angles are 1 – 7 and 2 – 8.

III. Alternate interior angles: thepairs of angleson opposite sides of the transversal, but inside the two lines, are called alternate interior angles. If the two lines are parallel, the alternate interior angles are equal. Here, the altenate interior angles are 3 – 5 and 4 – 6.

IV. Interior angles on the same side of the transversal: as the name suggests, they are the interior angles that lie on the same side of the transversal. Here, the interior angles on the same side of the transversal are 3 – 6 and 4 – 5.
