Morphology

equilateral = lateral (transparent) = equi + lateral

Built from equi- ('equal') + lateral ('side'); the meaning 'having equal sides' follows directly from these components.

Etymology

Equilateral comes from two parts: equi- meaning 'equal' and lateral meaning 'side', and equi- is the same root as the word equal; so an equilateral shape has all its sides the same length.
