Question
Complete the table below for the points A, B, C, and D after they have been rotated 180° anticlockwise about the origin. Coordinates beforeCoordinates afterA(0,6)(, )B(1,0)(, )C(1,6)(, )D(0,0)(, ) Submit answer
Solution
When a point is rotated 180° anticlockwise about the origin, the coordinates of the point change from (x, y) to (-x, -y).
So, the coordinates after rotation will be:
A(0,6) will become (0, -6) B(1,0) will become (-1, 0) C(1,6) will become (-1, -6) D(0,0) will remain the same (0,0) because it's the origin point.
So, the completed table is:
| Coordinates before | Coordinates after |
|---|---|
| A(0,6) | A(0, -6) |
| B(1,0) | B(-1, 0) |
| C(1,6) | C(-1, -6) |
| D(0,0) | D(0, 0) |
