1. TRANSFORMATIONS
Dianna Ramirez

2. Texas Essential Knowledge and Skills for 2nd grade
 Apply transformations and use symmetry and analyze mathematical situations
• Predict and describe the results of sliding (translations), flipping (reflections) and turning (rotations) two-dimensional shapes.

3. Transformations
A Transformation is Changing a shape using: • Turn • Flip • Slide, or • Resize

6. Translation Translation" simply means Moving,
without rotating, resizing or anything else, just moving.
Every point of the shape must move:
the same distance
in the same direction.

9. Reflections Every point is the same distance from the central line !
An image or shape as it would be seen in a mirror.
Every point is the same distance from the central line !
... and ...
The reflection has the same size as the original image
The central line is called the Mirror Line

12. Rotation
"Rotation" means turning around a center:
The distance from the center to any point on the shape stays the same.
Every point makes a circle around the center:
