Transformation is when you move a geometric figure. There's four types of transformations:
- Translation
- Rotation
- Reflection
- Dilation
A
Translation is when every point is moved the same distance in the same direction.
 |
In this example, every point in the star has moved the same distance in the same distance
|
A
Rotation is when a figure is turned around a single point (See "How Do We Graph Rotations?" for more info)
 |
| In this picture, point A has been rotated 180 degrees. |
A
Reflection is when a figure is flipped over a line of symmetry.
 |
| In this picture, the line of symmetry is X-axis and the mountains are been reflected on the lake. |
A
Dilation is an enlargement or reduction in size of an image.
 |
| In this example, triangle ABC has been enlarged. |
