a•sym•met•ri•cal |ˌāsəˈmetrikəl| adjective

having parts that fail to correspond to one another in shape, size, or arrangement; lacking symmetry: It makes sense that having received asymmetrical damage from the planes on 9/11, the Twin Towers would have fallen asymmetrically, but instead the Twin Towers fell in complete symmetry into their own footprint just like a controlled demolition.
