\ \ [15] Etymologically, triangles that are congruentcome together’ or ‘agree’ – that is, are similar. The word comes from congruēns, the present participle of Latin congruerecome together, meet, agree’. This was a compound verb formed from the prefix com- ‘together’ and a verb, *gruere, not found elsewhere (some have linked it with Latin ruerefall’ – ultimate source of English ruin – in which case congruere would have meant literally ‘fall together’, but others have seen a connection with Greek zakhrēēsattacking violently’). Incongruous is a 17thcentury adoption from Latin incongruus.
