Тут всё просто. "asas" мы используем когда хотим сказать что кто-то или что-то такое же.
Например она такая же красивая как и её мама. She is as beautiful as her mother.
Тоесть мы с двух сторон прилагающиего ставим as, а форму не меняем (посмотри на пример).
"than" мы используем что бы сказать что что-то, или кто-то лучше, что бы сравнить. Например он красивее неё. He is more beautiful than her.
А как менять слова нужно просто запомнить. Например:
good – better – best; bad – worse – worst; little – less – least;
