Crystal is amazed! She graphed ΔABC using the points A(5, −1), B(3, −7), and C(6, −2). Then she rotated ΔABC 90° counterclockwise () about the origin to find ΔA′B′C′. Meanwhile, her teammate took a different triangle (ΔTUV) and rotated it 90° clockwise () about the origin to find ΔT′U′V′. Amazingly, ΔA′B′C′ and ΔT′U′V′ ended up using exactly the same points! Name the coordinates of the vertices of ΔTUV.Homework Help ✎
