Morphology
The compound is a straightforward composition: 'square' denotes the right‑angle tool and 'set' marks it as a particular/fixed type, so the overall meaning — a specific square used for drawing/checking angles — is directly inferable from the parts. This follows regular English noun + modifier composition and is likely transparent to a B1 learner who knows both constituents.
Etymology
Set square is named for what the tool does: it helps you set a square, a 'right angle', on paper or wood. That's why set square means the tool used to draw and check 'right angles'.
