Transformation

Aim: How Do We Identify Transformations?

A Transformation is when you move a geometric figure.
-Their are four types of Transformations which are:

-Translation

-Reflection

-Rotation

-Dilation

-A Translation is when every point is moved to the same distance in the same direction.
Examples: 










-A Reflection  is when a figure is flipped over a line of symmetry.
Examples:




-A Rotation is when a figure is turned around a single point.

Examples:

-A Dilation is an enlargment or a reduction in the size of an image.
Examples:
