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 ΔABC′. Meanwhile, her teammate took a different triangle (ΔTUV) and rotated it 90° clockwise (↻) about the origin to find ΔTUV′. Amazingly, ΔABC′ and ΔTUV′ ended up having exactly the same points! Name the coordinates of the vertices of ΔTUV. 10-13 HW eTool (Desmos). Homework Help ✎
