'angulating' originates from English, from the verb 'angulate,' which ultimately comes from Latin 'angulatus' (past participle of 'angulare') based on 'angulus' meaning 'angle.'

'angulatus' in Latin (from 'angulus' ‘angle’) influenced the English formation 'angulate' in Early Modern English, which then formed the modern English participle 'angulating' with the suffix '-ing'.

Initially, it meant ‘to make angular or form an angle,’ and in modern usage it retains this sense, often in technical or medical contexts.
