If A, B, C and D are four points such that BAC = 45° and BDC = 45°, then A, B, C, D are con cyclic.

TRUE

In geometry, a set of points are said to be concyclic if they lie on a common circle.

Given: ∠BAC = ∠BDC = 45°

Since, angles in the same segment are equal, therefore A, B, C and D are concyclic.
