IPA: /θiˈɒdəlaɪt/
KK: /θiˈɑːdəˌlaɪt/
A tool used by surveyors that has a telescope and can rotate to measure angles in different directions.
The surveyor used a theodolite to accurately measure the angles of the land.
The word 'theodolite' is derived from the Greek 'thea' (meaning to view) and 'dolos' (meaning a small instrument or tool). The term combines these roots to describe an instrument used for viewing angles in surveying.
Think of 'viewing' ('thea') with a 'small tool' ('dolos') — that's how a theodolite helps surveyors measure angles.
