Permutation

can someone help me under stand this please?

A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. Each possible arrangement would be an example of a permutation.

The complete list of possible permutations would be:

AB, AC, BA, BC, CA, and CB.

Permutation is used for lists (order matters) and Combination for groups (order doesn't matter). Famous joke for the difference is: A “combination lock” should really be called a “permutation lock”. The order you put in the numbers of lock matters.

aa (angle angle)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
