Which statement is true about a translation?

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

A translation requires a line of translation.

A translation requires a center of translation.

8.G.1.b

Lines l and m are perpendicular. A point Q has this property: rotating Q 180 degrees using center P has the same effect as reflecting Q over line m.

Give two possible locations of Q.
Do all points in the plane have this property?
