1. Transformations on the Coordinate Plane
I can tell you what it’s not!!!
WHAT IS THAT?
TRANSFORMATION?

2. Translation
Sliding a figure in a straight line is called a translation.

3. Reflection
Flipping a figure over a line is called a reflection.

4. Reflection
Just like a baby seeing themselves in a mirror, the image of a triangle will be reflected when it crosses another line.

5. Rotation
Turning a figure around a point or vertex is called rotation.

6. Rotation

7. Transformation
What will change when you transform a figure on the coordinate plane?
its position
What will not change?
its size and shape

8. Translate, rotate, or reflect
Transformation
What three ways can you transform a figure on a coordinate plane?
Translate, rotate, or reflect

9. Transformation
I have a triangle on a coordinate plane. I plan to transform it by translating it and reflecting it. How will the triangles be the same?
Both transformations result in a new congruent triangle.
A translations slides the new figure to a new location.
A reflection flips the new triangle over a line to a new location.
