Symmetry and Transformations
Transformation
Movement of an original geometric shape to another according to a predefined rule
Reflection
Each point of the figure’s image is the same distance from the line of reflection as the corresponding point of the preimage.
Try it Out!
Translation
A reflection through a pair of parallel lines.
Try it Out!
Rotation
Reflecting a figure through each of two intersecting lines in succession.
Try it Out!
Symmetry
Line- each half of the figure is a reflection of the other half.
Rotational- during a rotation of less than 360 around a center point, the image coincides with the original figure.
Point- 180 rotational symmetry.
Symmetry- What does it look like?
