In the following figure, what can be concluded from the given conditions.
Given: AB = CD and AC = DE.
All of the above.
Given that chords AB and CD are equal.
Therefore, the angles subtended by them at the centre are also equal.
∠AOB = ∠COD
We can write ∠AOB = ∠AOC + ∠COB _________1
Similarly we can write ∠COD = ∠COB + ∠BOD ________2
From (1) and (2)
∠AOB = ∠COD
∠AOC + ∠COB = ∠COB + ∠BOD
Therefore, ∠AOC = ∠BOD
Therefore using converse of theorem, we get AC = BD.
Hence all the three given options are correct.
