What is Parsec and Parallax?

-

 Let's find out how to measure the distance from Earth to any star.

>>>>>>>>> Parsec Parallax <<<<<<<<<<<<<<<<<

But first you shall know how to measure angles.

1. Read this: 90°11`41``

This is 90 degrees, 11 arcminutes, and 41 arcseconds

2. Is this correct? Why?
51°20`90`` 

No. Arcseconds and arcminutes cannot be greater than 60!

90`` -> 1`30``

51°20`90`` -> 51°21`30``

Arcminutes and arcseconds are just like minutes and seconds on the clock!
