Topology is about non-metric space properties {topology}| {analysis situs}.
properties
Open-set space properties are continuity, proximity, homeomorphy, and invariance under transformation {topological property}. Topological properties are invariant if figures bend, stretch, shrink, or deform without creating or losing points and nearby points are still nearby. Being a curve is invariant topological property. Space dimension is an invariant topological property.
not properties
Size, shape, angle, or length are not open-set space properties and are not topological properties.
