Parallax Method to determine the distance of stars

WHAT IS THE WAY TO MEASURE THE DISTANCE OF DISTANT OBJECTS LIKE STARS WITH THE HELP OF PARALLAX METHOD

SHWETANSU asked.

Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.

Astronomers use the principle of parallax to measure distances to celestial objects including to the Moon, the Sun, and to stars beyond the Solar System.

See the animation below to understand the parallax method for determining the stellar distances

Aswin Ramesh Asked (via email)
is it the same method that we use in trigonometry ?
 Answer:
Parallax is a different concept, though we are using the principle of trigonometry to solve problems based on it.
