Sorry, to jump in where I have very little knowledge and understanding,

to have the sum change the distribution if it's identical. Isn't it
multiply that makes it triangular?
If you add two normal random variables, you produce a normal random
variable. This is not true of any other distribution. Use of "rand,"
as in the example, makes uniform (not normal) variates, so their sum is
also non-normal.
