Actually, you would have to take your angle measurement and subtract from 90° to get your latitude. Also, there is a straw on top of my protractor to assist with the aiming—and it looks cool.

(A goniometer measures plane angles.) These instruments, along with a stereographic protractor and beam compasses that Penfield patented in 1901, helped establish the technique of stereographic ...

But you don’t have to break out the protractor; you can easily use a level to determine the angle of the cut.

This Pi-powered protractor is intended to be used to calculate rotational angles in real time. This particular module is able to convert said measurement into a USB signal which makes it an ...

From there, surveyors eye the summit and measure the angle with the assistance of a glorified, highly accurate protractor — a telescopic device known as a theodolite.
