Morphology

congruent = con + gru + ent

The adjective is historically built from con- + a combining root + -ent, and while the sense 'coinciding' relates to 'together', the precise mathematical meaning 'same shape and size' is a specialized usage that many learners would not derive from the pieces alone.

Etymology

Congruent comes from Latin parts con- 'together' and gruere 'to fit'. So congruent describes shapes that 'fit together' exactly, which is why they match when you put one on top of another.
