Finite shapes cannot have these types of symmetry. Classification of shapes based on symmetry. Shapes can be classified according to their symmetry. To do so (for finite shapes, like polygons), count the number of lines of (reflection) symmetry, if any, and determine the (smallest) angle of rotation symmetry, if any.
Refinancing transactions might be completed within 30 days; however, 60 to 90-day time frames are more plausible. A lender's loan volume, workforce and other circumstances could impact processing speeds. You can ask your loan officer about the estimated time frame for refinancing your mortgage.
