How do i measure star angles ?

Question

EXPLANATION TO MY LAST QUESTION

this is what i need

length and height of bowl of big dipper

length and height of polaris

length of handle of big dipper

distance from big dipper to Polaris

width of cassiopia

distance from polaris to cassiopeia

Answer 1

One’s own hand can be used to estimate angular widths in the sky.

Hold at arm’s length, palm outward:

Width of: Approximate degree of arc

little finger: 1

index, middle, and ring fingers: 5

fist: 10

little and index fingers stretched apart: 15

little finger and thumb stretched apart: 25  

Answer 2

I don't think using constellations is a good way of measuring angles to stars.  A star in a constellation could be 7 light years away and another star in the same constellation could be 7000 light years away.  What format would you like this answer in and I will get it for you?

Ok I did my best to get this answer.  

Length of bowl of big dipper in degrees is 7.87

Height = 5.42

Handle of big dipper is 12.21

Width of Cassiopeia is 13.27

Cassiopeia to Polaris is 27.19

Big Dipper to Polaris 33.44

Length of Ursa minor 17.93

height 3.18

Polaris is a star and not a constellation btw
