From the diagram given below, what is the relation between ∠BAC and ∠BCD?(a) ∠BAD = ∠BCD(b) ∠BAD = 2∠BCD(c) ∠BAD = 0.5∠BCD(d) ∠BAD = 3∠BCDThe question was asked in a job interview.The above asked question is from Angle Subtended by an Arc of a Circle in division Circles of Mathematics – Class 9

Answer»

Correct answer is (a) ∠BAD = ∠BCD

The best EXPLANATION: ACCORDING to theorem 10.9, angles in the same SEGMENT are same.

We can SEE that angles ∠BAC and ∠BCD are in the same segment and hence ∠BAD = ∠BCD.
