congruent
what are the 2 directions that a rotation can go in?
clockwise and counterclockwise
when you flip over the x axis the _____ coordinate does not change
the x coordinate
up and down
vertical
The transformation used when a figure is moved without turning it to slide
translation
when you move left or right for a translation you are on the _______________ axis
x axis
how many jumps is a 180, 270, 90 and 360 in that order?
2, 3,1,4
when you flip over the y axis the _______ coordinate does not change

horizontal
When a mirror image is produced by flipping a figure over a line
give me the rule with the correct notation for 5 units to the left and 2 units up
(x-5) (y+2)
at what 2 degrees does the x and y switch places
90 and 270
when you flip over the x axis the x will stay the same and the y _________________
will become opposite sign
figures that are the same size and shape
congruent
3 examples of this are reflection, rotation, and tranlsation
transformation

when you flip over the y axis the y does not change but the x coordinate__________________
will have the opposite sign
