Answer the following statement(s) true (T) or false (F)
1. If a similitude takes ?ABC to ?A'B'C' so that A'B'/AB = 5, then the ratio of the area of ?A'B'C to the area of ?ABC is 5. 2. The reflection with respect to maps square ABCD onto itself. 3. Every glide reflection has at least one fixed point. 4. Size transformations are the one type of transformation that does not have an identity transformation. 5. All polygons have n reflections onto themselves. 6. If A'B'C' is the image of ?ABC under a similitude, then the area of ?A'B'C is the same as the area of ?ABC.
