Viral optical illusion: Is this a 2D building? Netizens are confused!

An optical illusion of a 3D triangular building resembling a 2D glass sheet has gone viral, leaving viewers confused. The image features multiple buildings, with a slim and thin glass-like panel standing among them, that looks like a flat sheet at first glance but reveals itself as a 3D structure later. A Reddit user explained that the building looks like a triangle when viewed from one side, but appears flat due to the viewer’s angle.
