- For the first shape (top-left), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,3), (1,1), and (4,1). After rotation, they become (3,-1), (1,-1), and (1,-4). Plot these new points and connect them to form the rotated triangle.
- For the second shape (top-right), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,0), (2,3), and (4,1). After rotation, they become (0,-1), (3,-2), and (1,-4). Plot these new points and connect them to form the rotated triangle.
- For the third shape (bottom-left), rotate each vertex 90° clockwise about (0,0). The original vertices are approximately (1,2), (3,1), and (5,2). After rotation, they become (2,-1), (1,-3), and (2,-5). Plot these new points and connect them to form the rotated triangle.
- For the fourth shape (bottom-right), rotate each vertex 90° counterclockwise about (0,0). The original vertices are approximately (2,1), (2,3), and (4,1). After rotation, they become (-1,2), (-3,2), and (-1,4). Plot these new points and connect them to form the rotated triangle.
Parent Tip: Review the logic above to help your child master the concept of rotation worksheet grade 8.
