Triangle Pose — Trikonasana (tree-koh-NAH-suh-nuh) — is a standing yoga pose that tones the legs, reduces stress, and increases stability. The word "Trikonasana" comes from the Sanskrit words "tri," (meaning "three"), "kona"(meaning "angle"), and "asana" (meaning "pose"). It refers to the triangular shape created by your body in the full version of the pose. "Utthita" means "extended" in Sanskrit.
