As already explained, they used to be measured using triangulation. These measurements, while pretty darned close, always ended up being estimates, due to limitations of the equipment used.
Now satellite-based lasers are used to measure mountain height to within a few inches.

This is really a vague question.
I recall an experiment where some clever dude measured the MASS of a mountain by measuring the defelction of a metal ball in the direction of the mount, measured against the deflection on the opposite side and aligned against a star!
Does this help?

Starting from Newquay in Cornwall you measure the hieght above sea level using a theodolite and staffs called flying heights, or from the known point i.e. a datum point found on a map and shown on the kerb stones or side walls of buildings.

You use a barometer. Altimeters are all barometric i believe. You can estimate altitude with a GPS system but barometric altimeters are more accurate.

By triangulation, starting from a known point.
