21 sty 2020 · The four most common reflections are defined below: Common Reflections About the Origin. Reflection Symmetry. Additionally, symmetry is another form of a reflective transformation. When a figure can be mapped (folded or flipped) onto itself by a reflection, then the figure has a line of symmetry.

Reflection over the y-axis. A reflection in the y-axis can be seen in diagram 4, in which A is reflected to its image A'. The general rule for a reflection over the y-axis $ r_{y-axis} \\ (A,B) \rightarrow (-A, B) $
TRANSLATIONS: Translations are a slide or shift. Translations can be achieved by performing two composite reflections over parallel lines. Translations are isometric, and preserve orientation. Coordinate plane rules: (x, y) (x ± h, y ± k) where h and k are the horizontal and vertical shifts.
Use models or points in the coordinate plane to illustrate, recognize, or describe rigid transformations (translations, reflections, and rotations) of plane figures.
Explore translations, reflections and rotations and find rules for reflecting and rotating.
