Morphology

scalene + triangle

The adjective 'scalene' explicitly denotes a triangle with three unequal sides, so when combined with 'triangle' the meaning is directly compositional as an adjective + noun phrase. This standard morphological pattern is cross-linguistically common, so a B1 learner who knows both constituent words will understand the MWE.

Etymology

Scalene triangle comes from the Greek word 'skalenos', meaning 'unequal'. The word scalene gives a clear picture: a triangle with all sides (and angles) different, so it means 'a triangle with all sides of different lengths'.
