I am taking geometry right now...and i have a simle question..?

Question

Ok so if you know alot about geometry and you are good at it..then you should be able to help me.

Is this true or false?

{a,b,c} = {c,b,a}

i don't know if they have to be in the same order to be equal.

Answer 1

This is considereed an ordered triplet and like all ordered groups the answer is yes it makes a difference.

Typically an ordered triplet is asking to identify a point in space.

Consider where a=0, b=1 and c=2

(0,1,2) will not equal (2,1,0)

Answer 2

True

{a,b,c} = {c,b,a}

the sets have the same elements
