Does katniss use her bow and arrow to trigger the mines?

No, Katniss does not use her bow and arrow to trigger the mines in the Hunger Games.

While Katniss is an expert with her bow and arrow, the mines in the Games are designed to be triggered by pressure or movement, not projectiles.

The mines are used strategically throughout the series, particularly in the later books, but Katniss relies on her archery skills for hunting and combat, not for manipulating explosives.
