Definition:
If you're talking about adjective, like in parts of speech, then the word 'right' is the adjective, describing the noun 'triangle'.
Adjectives are used to describe a noun. They commonly come right before the noun that they are describing, though that is not always the case (i.e. predicate adjective and subject).
The suffix -ig in German often indicates that the word is an adjective describing a characteristic or quality, similar to the English suffix -y or -ly. It can turn a noun into an adjective, such as "sauer" (sour) from "die Saure" (acid) or "aktiv" (active) from "die Aktivität" (activity).
