고대 그리스 사람들은 기하학을 아주 체계적으로 발전시켰어요.
[kotɛ kɯlisɯ salamtɯlɯn kiahakɯl at͡ɕu t͡ɕʰekjet͡ɕʌkɯlo palt͡ɕʌnsikʰjʌs͈ʌjo.]
The ancient Greeks developed geometry very systematically.
건축을 공부하려면 기하학에 대한 기초 지식이 반드시 필요해요.
[kʌnt͡ɕʰukɯl koŋpualjʌmjʌn kiahake tɛan kit͡ɕʰo t͡ɕisiki pantɯsi pʰiljoɛjo.]
To study architecture, you definitely need a basic knowledge of geometry.
솔직히 학창 시절에 기하학만큼 어려운 과목은 없었던 것 같아요.
[solt͡ɕikʰi hakt͡ɕʰaŋ sit͡ɕʌle kiahakmankʰɯm ʌljʌun kwamokɯn ʌps͈ʌtt͈ʌn kʌs katʰajo.]
Honestly, I don't think any subject was as hard as geometry when I was in school.
