Nouns and adjectives agree in case, number and gender. Sometimes the endings for these will look the same. Quite often they will not.
So focus on matching case and number, not the endings, or you will experience pain in the future.
There is, for example, a very large class of adjectives where the masculine and feminine forms are identical.
Somehow you posted this question three times. I blotted out two of them.
