Morphology
The meaning 'branch of geometry dealing with shapes in a two-dimensional plane' is directly and transparently composed from 'plane' (a flat two-dimensional surface) + 'geometry' (mathematics of shapes and their properties). This straightforward noun-noun composition and cross-linguistic equivalence make the sense immediately deducible for a B1 learner who knows both constituent words.
Etymology
Plane geometry comes from plane meaning a flat surface and geometry meaning the study of shapes. It creates the image of drawing lines, circles and polygons on one flat area, so it means the study of 'flat' or 'two-dimensional' figures.
