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.

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

6. On your graph paper, translate (slide) the leaf 3 units left and 2 units down . What are the new coordinates of the leaf?
