Morphology
The meaning is directly derivable from the parts: 'go off' (move away/deviate) + 'on tangent(s)' (a departure from the main subject), so together they literally describe moving away from the main topic. This motion-metaphor composition is cross-linguistically common and follows standard English verb + prepositional phrase patterns, so a B1 learner who knows the constituents would readily infer the meaning.
Etymology
Go off on tangents comes from math: a tangent is a straight line that just touches a circle once and then moves away. That's why to go off on tangents means 'to start talking about ideas that move away from the main topic'.
