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 |
Scale factor < 1 = _____________ | Reduced |
Scale factor = 1 = ____________ | Stays the same |
