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) |
