1. Transformations Main Idea Notes Transformation
Changes the position or orientation of a figure.
There are 4 types of transformations.

2. Transformations Main Idea Notes Congruent Symbol: ≅
Means that figures are exactly the same size and shape.
The first 3 transformations are congruent to the original figure.

Translation
Figure slides along a straight line without turning.

4. Example of a Translation on the Coordinate Plane
The figure slides along a straight line.

Reading Math:
A’ read “A prime” is used to represent the point on the image that corresponds to point A on the original figure (pre-image).

Flip
4 Types of Transformations
Main Idea
Notes
Reflection
Figure flips across a line of reflection (x or y-axis), creating a mirror image.

6. Example of a Reflection on the Coordinate Plane
The figure flips across the y-axis.

Rotation
Figure turns around a fixed point (origin).

8. Example of a Rotation in the Coordinate Planey
The figure turns around a fixed point.

9. Transformations Main Idea Notes Similar Symbol: ∼
Means that figures have the same shape but are not necessarily the same size.
The 4th transformation is similar to the original figure.

10. 4 Types of Transformations
Dilation
4 Types of Transformations
Main Idea
Notes
Dilation
Figure’s size changes (bigger or smaller).

11. Example of a Dilation on the Coordinate Plane
The figure is enlarged.
