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.
