Symmetrically → It is formed from "sym-" (from Greek "symmetricos", meaning together or with) and "metron" (meaning measure), along with the suffix "-ically" (meaning in a manner). The word "symmetrically" refers to something that is measured or arranged in a balanced and proportionate way, together.
Think of things that are 'together' ('sym-') and 'measured' ('metron') in a balanced way — that's what symmetrically means.
