Transit Theodolite

What is the difference between a theodolite and a transit?
They are the same thing. Europeans tend to say “theodolite”, which is the older term. Americans tend to say “transit.” It’s the tripod thing you see surveyors toting around. You use it to measure how much one point you’re standing on is higher/lower than another point you can see.
Here’s what the Wikipedia has to say about theodolites/transits: (more at the wikipedia article URL below.)
A theodolite (Amer. “transit”) is an instrument for measuring both horizontal and vertical angles, as used in triangulation networks. It consists of a telescope mounted movably within two perpendicular axes, the horizontal or trunnion axis, and the vertical axis. These must be mutually perpendicular. The condition where they deviate from perpendicularity (and the amount by which) is referred to as horizontal axis error.
