I'm not sure if you're missing a "NOT" in the question, or the wording is wrong, but three of these are theorems or postulates used to prove triangles congruent, while one is not.
Angle-side-angle (ASA) is used when two angles and an included side are congruent, side-side-side (SSS) is used when all three sides are congruent, and side-angle-side (SAS) is used when two sides and an included angle are congruent. All these are theorems or postulates used to prove triangles congruent.
Angle-angle-angle (AAA), however, is not.
I hope this helps you.

Explanation:
Most of the world, in order to produce energy for whatever purpose, mostly relies on usage of fossil fuels. The fossil fuels that are the most dominant when it comes to usage are unfortunatelly the ones that cause the most pollution. Those two fossil fuels are the coal and oil. There is another fossil fuels though that has always been in the background but is gradually becoming more and more popular.
The fossil fuel that starts to gain more ground is the natural gas. The natural gas is relatively abundant, easy for usage, transportation, and economically justifiable. What is also very important and gives it an advantage lately is the fact that the pollution form it is uncompearably lower, in fact, the methane that is released from the natural gas only does so because of leaks during its transportation.
