Strand: Geometry Standard 9: Transformation of Shapes (Symmetry, Reflection, Translation) Standard 10: Coordinate Geometry

Strand: Geometry Standard 9: Transformation of Shapes (Symmetry, Reflection, Translation) Standard 10: Coordinate Geometry Shapes with Line Symmetry have a line or a fold that make two reflecting parts. Looking at symmetrical sides, each point will have a corresponding reflection point on the other side.

Translation is the process of sliding a picture to a new location, without rotation,

Translation is the process of sliding a picture to a new location, without rotation, reflection or changing its shape or size.
