Angry means full of hot feeling because something is unfair or wrong. Get angry, angry about it, an angry crowd.
The prepositions matter: angry with a person, angry about a thing, angry at either in American use. Of a wound or a sky it means red and inflamed: an angry scar, angry clouds. Note anger, the noun; cross, which is the milder British word; and that mad means angry in America and insane in Britain, which is one of the sharper transatlantic differences.
