Transformations and Dilations TEST

What is a translation in geometry?

• A type of rotation in a figure

• A transformation that moves every point of a figure the same distance and in the same direction.

• A transformation that changes the size of a figure

• A reflection across a line in a figure

What is the difference between a reflection and a rotation?

• A reflection is a translation, while a rotation is a dilation.

• A reflection is a slide, while a rotation is a stretch.

• A reflection is a turn around a point, while a rotation is a flip over a line.
