Each question consists of two statements, namely, Assertion (A) and Reason (R). Choose the correct option.

Assertion (A)	Reason (R)
If two lines AB and CD intersect at O such that ∠AOC = 40°, then ∠BOC = 140°.	If two straight lines intersect each other, then vertically opposite angles are equal.

Assertion (A)

Reason (R)

If a ray stands on a line such that ∠ACD = ∠BCD, then ∠ACD = 90°.

If a ray stands on a line then ∠ACD + ∠BCD = 180°.

Assertion (A)

Reason (R)

If the side BC of a ΔABC is produced to D, then ∠ACD = ∠A + ∠B.

The sum of the angles of a triangle is 180°.

Assertion (A)

Reason (R)

If AB || CD and t is the transversal as shown, then ∠3 = ∠5.

If a ray stands on a straight line the sum of the adjacent angles so formed is 180°.
