Transformations
| Term | a transformation described as |
|---|---|
| Translation | a transformation of a figure described as a slide |
| Reflection | a transformation of a figure described as a flip |
| Rotation | a transformation of a figure described as a turn |
| Scale Factor | common multiplicative ratio between pairs of related data which may be represented by a unit rate |
| Similar Shapes | shapes whose corresponding angles are congruent and corresponding sides are proportional |
| Dilation | an enlargement or reduction on a figure using a scale factor. The new shape is similar and in proportion to the original shape. |
| Center of Dilation | a coordinate point that serves as the focal point for generating a dilation |
| Orientation | figure preserves the way it looks |
| Congruency | the figure preserves its size |
| Reflection of the X-Axis | ((x, -y) |
| Reflection over the Y-Axis | (-x, y) |
| 90* Counterclockwise/270* CW | (-y, x) |
| 90* Clockwise/270* CCW | (y, -x) |
| 180* | (-x, -y) |
| Example of Enlargement | (2x,2y) |
| Example of Reduction | (1/2 x, 1/2 y) |
| Example of a Translation | (x+4,y-2) |
