- For the first shape, rotate 90° clockwise about (3,1): Each vertex of the triangle is moved such that its position relative to (3,1) is rotated 90° clockwise. The new vertices are approximately at (4,0), (6,-1), and (5,-3).
- For the second shape, rotate 90° clockwise about (3,-3): Each vertex is rotated 90° clockwise around (3,-3). The new vertices are approximately at (5,-2), (7,-1), and (8,-4).
- For the third shape, rotate 90° counterclockwise about (1,0): Each vertex is rotated 90° counterclockwise around (1,0). The new vertices are approximately at (0,2), (-2,3), and (-1,5).
- For the fourth shape, rotate 180° about (2,-4): Each vertex is rotated 180° around (2,-4), which is equivalent to reflecting through the point. The new vertices are approximately at (3,-3), (5,-5), and (4,-7).
