In the diagram, ABC congruent to DEF. Find a sequence of
rigid motions that maps ABC to DEF.
A rotation of 90 counterclockwise is needed to map
ABC to DEF.

The coordinates of the image are A' (_,_), В' (_,_), and C (_,_).

The translation that maps A'B'C to DEF is
(x,y) → (__,__).
The sequence of rigid motions that maps ABC to DEF is a rotation _.
counterclockwise followed by a translation _
unit(s) to the __ and
_ unit(s)- ___.
