Go watch this video.

TAKE NOTES.

You need to know rotation, translation, and reflection.

Sliding the shape in the coordinates plane by moving it:

Right (+) or Left (-) (on x Axis)

Up (+) or down (-) (on y Axis)

All points move same distance.

TRanslations

TRanslation Rule

In this example we can write the rule as:

Take notes.

Rotation = Turn

Reflection =Flip

Translation = Slide

Dilation = Enlarge/Reduce

tHERE ARE 4 TYPES OF trNASFORMATIONS

Take notes.
