SAS Triangle Similarity Theorem

In the triangles below..[br]There is 1 set of corresponding congruent angles (Angle C & Angle F)[br]AND[br]There are 2 sets of corresponding proportional sides (AC/DF & BC/EF)

Name and perform the transformation the will map C onto F.

Name and perform the transformation that will map C'B' onto EF. (Hint: The measure of Angle B'C'E is 80 degrees.)

Name and perform the transformation that will map C"A" onto DF.

Lastly, name and perform the operation that maps B''' onto E. (Hint: The scale factor is 2.)

How do you know that this last transformation will also map A''' onto D?
