How do we identify Transformations?

Aim: How do we identify Transformations?

Transformations are when you move a geometric figure.

There are 4 transformations
-Rotations
-Dilations
-Reflexions
-Translations

-A Translation is when every point is moved the same distance and same direction.
Example: From each point of the triangle move Five units to the right and 3 units down.


-A Dilation is the enlargement or reduction in the size and image.
Example:


-An Rotation is when a figure is turned around a single point.
Example: Move each point 90 degrees Counterclockwise.

- A Reflection is when a figure can be flipped over a line of symmetry.
Example:

Question:

	This graph illustrates a reflection over the x-axis. True False
	Explanation If you folded the graph along the x-axis, the figures would coincide.
