Ireally need on this, i'm giving out 30 points.

if a series of rigid transformations maps ∠e onto ∠b where ∠e is congruent to ∠b, then which of the following statements is true?

triangles abc and fde, in which angles a and d are right angles

δabc ~ δfde because of the definition of similarity in terms of similarity transformations
segment de ~ segment ab because corresponding parts of similar triangles are similar
δabc ~ δfde because of the aa similarity postulate
segment de ~ segment ab because of the definition of similarity in terms of similarity transformations
