Morphology

bilateral = lateral (transparent) = bi + lateral

The composition 'bi-' (two) + 'lateral' (sides) transparently gives the sense of having two matching sides.

Etymology

Bilateral comes from the parts bi- ('two') and lateral ('side'). Think of a face or a leaf with the same shape on the left and the right; that's bilateral symmetry, so something bilateral has matching parts on both sides.
