Answer: 3. Point F.
Explanation:
 The missing statement is: Point F' corresponds to______
- Point D.
- Point E'.
- Point F.
- Point E.
 The missing picture is attached.
 By definition, the original figure (The figure before the transformation) is called "Pre-image" and the figure obtained after the transformation is called "Image".
 You know that the triangle 
 is obtained by transforming the triangle
 is obtained by transforming the triangle 
 ; therefore, the triangle
; therefore, the triangle 
 is the Pre-Image and the triangle
 is the Pre-Image and the triangle 
 is the Image.
 is the Image.
 Therefore, given the point 
 (which is a vertex on the triangle
 (which is a vertex on the triangle 
 ) you can identify that its image is
) you can identify that its image is 
 (which is the corresponding vertex on the triangle
 (which is the corresponding vertex on the triangle 
 ).
). 
 You can also verify it by seeing the angle 
 and the angle
 and the angle 
 . Notice tthat:
. Notice tthat:
 

 Therefore, based on the explained before, you can conclude that the point 
 corresponds to the point
 corresponds to the point 
 .
