A transformation in which a graph or geometric figure slides to another location
What is translation?
a figure that is translated 3 units left that starts at (0,0)
What is (-3,0)?
The point that (2,1) becomes when reflected across the y-axis.
What is (-2,1)?
This angle of rotation creates the same image if it's rotated clockwise or counterclockwise.
What is a rotation of 180 degrees?
Operations that alter the form of a figure. Examples: translations, reflections, and rotations.
What is transformations?
