Symmetry in everyday language refers to a sense of harmonious and beautiful proportion and balance. In mathematics, "symmetry" has a more precise definition, and is usually used to refer to an object that is invariant under some transformations; including translation, reflection, rotation or scaling.

Answer 2

Answer:

Having two halves that match each other exactly in size, shape, etc.

The corresponding body parts on both sides of a centred dividing line are in the same position to each other (mirror image between two halves of the body divided by the sagittal plane).
