Morphology
The meaning 'an angle that measures more than 90° and less than 180°' is directly and compositionally derived from 'obtuse' (an interior angle between 90° and 180°) modifying 'angle' (a geometric angle). This adjective–noun combination follows regular semantic composition and is cross-linguistically transparent (e.g. Spanish 'ángulo obtuso'), so a B1 learner who knows both constituents would readily understand it.
Etymology
The term obtuse angle uses obtuse to mean 'blunt' or 'not sharp' and angle to mean a corner, so picture a corner that opens wide instead of making a sharp point. That's why an obtuse angle means an angle larger than a right angle, more than 90 degrees but less than a straight line of 180 degrees.
