Question

what rigid motion maps the solid - line figure onto the dotted - line figure?
a. reflection
b. rotation
c. translation

Explanation:

Translation is a rigid - motion that moves every point of a figure the same distance in the same direction. The orientation and shape of the solid - line figure and the dotted - line figure are the same, just in different positions, which is characteristic of translation. A reflection would flip the figure over a line, and a rotation would turn the figure around a point.

Answer:

C. translation
