- For the first shape (top left), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,3), (3,3), and (3,1). After rotation, they become (3,-1), (3,-3), and (1,-3). Plot these new points and connect them to form the rotated triangle in the fourth quadrant.
- For the second shape (top right), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,1), (2,4), and (3,1). After rotation, they become (1,-1), (4,-2), and (1,-3). Plot these new points and connect them to form the rotated triangle in the fourth quadrant.
- For the third shape (bottom left), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,2), (3,2), and (4,1). After rotation, they become (2,-1), (2,-3), and (1,-4). Plot these new points and connect them to form the rotated triangle in the fourth quadrant.
- For the fourth shape (bottom right), rotate each vertex 90° counterclockwise about (0,0). The original vertices are approximately (2,2), (3,2), and (3,1). After rotation, they become (-2,2), (-2,3), and (-1,3). Plot these new points and connect them to form the rotated triangle in the second quadrant.
Parent Tip: Review the logic above to help your child master the concept of rotation worksheet.
