Answer #2:
Yes.
Another answer: The primary use of triangulation may not be to measure the distance of stars, but the method which is used to measure the distance of close stars is primarily triangulation.
The unit used is the astronomical unit, defined as the semimajor axis (mean radius) of the Earth's orbit. The distances are scaled according to Kepler's laws of planetary motion. The fundamental distance is the distance to Venus on a close approach, which was measured accurately by triangulation from two points on the Earth's surface during a transit.
Parallax is when objects seem to be in a different place, depending on the angle at which they are viewed. An example would be if you block an object in your visual field with one finger, then close your dominant eye. The object will appear to have moved. Triangulation, used in the context of mathematics and astronomy, is when you determine an unknown distance based on 2 or more known distances.
You should always measure your following distance by car length. This will give yourself time to break when necessary without being close to the driver ahead of you.
That depends how close you measure "the ocean". The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
That depends how close you measure to the bus. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
That depends how close you measure to the plane. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
