👉 In geometry, "non-verticalness" refers to a property of a geometric figure that does not follow the rule of verticality. In other words, it is a condition where an object or shape cannot be considered as straight and has no parallel lines. For example, in a right-angled triangle, if one angle is greater than 90 degrees (non-vertical), then this angle is nonvertical. Nonverticalness can be defined in terms of the properties of a figure such as its angles
