In the following figure which of the following statements is true? Correct Answer AC = CD

Answer: Option 2

In Triangle ABD,∠BAD + ∠B + 90° = 180° or, ∠BAD + ∠B = 90° - - - - - - - (1) Now, in Triangle ABC, ∠ACB + ∠B + ∠A = 180° ∠ACB + ∠B = 180° - 90° ∠ACB = 90° - ∠B - - - - - (2) From (1) and (2), ∠BAD = ∠ACB So, AC = CD
