180 degrees of rotation would have which rotation rule? (x,y) turns into (-x,-y)
A 270 degrees clockwise / 90 degrees counterclockwise rotation would have which rotation rule? (x,y) turns into (-y,x)
What is a transformation in which a figure is rotated, or turned, about a fixed point? Rotation
What is the technical term for the coordinates (0,0)? Origin
What transformation is a mirror image of the original figure? Reflection
When flipping over the x-axis what happens to the y-coordinate in a reflection? The y-coordinate becomes opposite
When flipping over the y-axis what happens to the x-coordinate in a reflection? The x-coordinate becomes opposite
What is the pre-image in a transformation? The original shape or image
What is the image in a transformation? What you get after the transformation
How does the figure change in a dilation? It changes size
what do you do to the coordinated during dilation? You multiply the coordinates by the scale factor
Scale factor > 1 = ___________ Enlarged
