Rigid Transformations and Sequence

The figure shows two perpendicular lines, and , intersecting at a point P in the interior of a trapezoid. Line is parallel to the bases and bisects both legs of the trapezoid. Line bisects both the bases of the trapezoid. Which transformation will carry the figure onto itself?

• 
• 
• 
• 

is shown the coordinate plane. It will be rotated 90 degrees clockwise about the origin to form . What will be the coordinates of and ?

will undergo a transformation to create \Delta J'K'L' in the xy coordinate plane. Which transformations will result in \Delta JKL\cong\Delta J'K'L'? Select all that apply.
