A rigid transformation transforms a preimage into a congruent image.
True
False
A 90° clockwise rotation is equivalent to a 90° counterclockwise rotation
True
False
If an image is reflected across the x-axis, the x-coordinates of the points do NOT change, only the y-coordinates will flip their sign
True
False
A dilation is an example of a nonrigid transformation because the shape stays the same but the size does not.
True
False
The translation (x, y) → (x - 1, y + 2) will translate the preimage 1 unit to the right and 2 units up.
True
False
A 360° rotation will map an image back to its original position.
True
False
The rule of reflection over the y-axis in mapping notation is (x, y) → (-x, y)
True
False
A rotation turns an image around an imaginary line
True
False
One way to find the scale factor of images in a dilation is to divide the x-coordinate of the preimage by the x-coordinate in the image.
True
False
Congruent figures have the same size and shape.
True
False
Rigid transformations change size.
True
False
Transformations NEVER change shape.
True
False
Transformations NEVER change size.
True
False
A rotation changes the size of the figure.
True
False
A reflection of a shape changes the size of the shape.
True
False
A translated figure is congruent to its preimage.
True
False
Reflected figures are NOT congruent to their preimage.

If the point (-3, 1) is REFLECTED across the x-axis, the translated point will be (-3, -1).
True
False
If the point (1, -1) is translated 2 units left and 5 units up, the new point will be (-1, 4).

When an image is reflected across the X-axis, what happens to the x-coordinates of the points?
