Geometry Transformation : Rotation
1. Suppose there is a point A (a,b). Then point A will be rotated
as far as 90° anticlockwise with the center of rotation of point
O (0,0).
2. Type in the input bar point (a,b), then enter
3. Type a point (0,0) on the input bar, then enter
4. Select rotate object around point on the angle menu
5. Then click the point to be rotated and the point used to be the
center of rotation. Then a dialog box will appear as below:
6. Specify the rotation angle, then click ok
Geometry Transformation : Translation
1. Suppose a point (a,b) will be translated t units horizontally to
the left
