Morphology

right-angled = right + angle (transparent) = right + angle + ed

Formed from the compound 'right' + 'angle' with the adjectival suffix '-ed', so its meaning is directly derived from 'right angle'.

Etymology

Right-angled comes from joining right, which long ago meant 'straight' or 'correct', and angle, meaning 'corner'. So a right-angled corner is the exact 'straight' corner you learn in geometry, a corner of 90 degrees.
