Transformations
This type of transformation means that shape keeps its original shape and size.
Isometric
Another word a rotation could be....
turn
Another word for reflection could be...
Flip
Another word for translation could be.....
slide or move

Which type of transformation keeps the object congruent and keeps the same orientation
Translation
If the scale factor is greater than 1 the image gets....
larger
What are the 3 Isometric Transformations
Rotation, Reflection, Translation

True or false: if a point is translated 4 units to the right and then translated again 4 units to the left, the point will end up in the same spot.
True
