📐 角度 = 角 (horn/angle) + 度 (degree/measure)
角 originally depicted an animal horn, later extended to any corner or angle. 度 means a measure or degree. Together they literally name the measure of an angle, then figuratively a viewpoint or perspective on something.
角 — pictograph of a horn
角 is a pictograph of an animal's horn, with early oracle-bone forms clearly showing the curved, ridged shape of a horn. From 'horn' it extended to mean corner, angle, and by metaphor a role or part (as in a stage role). The reading jiǎo covers most of these senses.
度 — 广 (shelter) + 庶 abbreviated (phonetic)
Originally depicted a hand measuring length under a shelter, meaning 'to measure' or 'a measure/standard.' From this came extended senses like 'degree,' 'extent,' and 'to pass through' (as in passing time). The reading 'dù' means degree/measure, while 'duó' preserves the older verbal sense of measuring.
