Transformations Vocabulary Math

What is the definition of "translation"?

• A transformation that moves every point of a figure the same distance and the same direction (slide). Shape, size, and orientation are preserved.

• A transformation that flips a figure over a line of reflection. Shape and size are preserved.

• A transformation that turns a figure around a fixed point. Shape and size are preserved.

• The number of degrees the figure rotates.

What is the definition of "reduction"?

• A dilation with a scale factor greater than 1 because the image is larger than the preimage
