Question

6 practice 9 (from unit 1, lesson 12)
which statement is true about a translation?
a a translation rotates a line.
b a translation takes a line to a parallel line or itself.
c a translation takes a line to a perpendicular line.
d a translation dilates a line.

Explanation:

A translation is a rigid - motion in geometry that slides a figure without rotating, dilating, or changing its orientation in terms of perpendicularity. It moves a line to a parallel line or to itself. Rotation rotates a line, dilation changes the length of a line, and a translation does not create a perpendicular relationship.

Answer:

B. A translation takes a line to a parallel line or itself.
