preimage (a,b)→ image (- a,- b) Using this rule on the vertices of ABCDE, we can find the vertices of A'B'C'D'E'.
| Point | (a,b) | (- a,- b) |
|---|---|---|
| A | (- 6,3) | (6,- 3) |
| B | (- 4,3) | (4,- 3) |
| C | (- 2,5) | (2,- 5) |
| D | (- 2,1) | (2,- 1) |
| E | (- 6,1) | (6,- 1) |
When we know the coordinates of the rotated shape, we can draw A'B'C'D'E'.
