Morphology
The noun phrase is fully compositional: 'isosceles' specifies the property (two equal sides) and 'triangle' names the three-sided figure, so the overall meaning follows directly from the constituents. This follows standard adjective + noun composition and is cross-linguistically transparent, so a B1 learner who knows both words will understand the term.
Etymology
Isosceles triangle comes from Greek words iso meaning 'equal' and skelos meaning 'leg', so it pictures a triangle with two 'equal' legs. That's why it means a triangle with two equal sides.
