cademy Justify triangle congruence Here is a rough outline of a proof that AABC E ADEF: 1 We can mapAABC using a sequence of rigid transformations so that A' = D and B' = E. (Show drawing 2. If C and F are on the same side of DE, then C = F. [Show drawing.) 3. If C and F are on opposite sides of DÉ, then we reflect AA' B'C' across DÉ and then C" =F. A" = D and B" = E.[Show drawing } TATUS What is the justification that C" = F in step 2? Choose 1 answer: C' and F are the same distance from E along the same ray. Both C and F lie on intersection points of circles centered at D and E with radii DF and EF, respectively. There are two such possible points, one on each side of DE. C' and F are at the intersection of the same pair of rays. Report a problem Stuck? Watch a video or use a hint. Do 4 problems 000 Check
