Question

fan/medal to whoever helps me
Triangle DEF has been dilated to form triangle D'E'F'. What is the least amount of information needed to determine if the two triangles are similar?

Answer 1

Angle F=F', angle E=E', and segments EC and E'C' are congruent.
Segment EC=E'C', segment DF=D'F', and angles E and E' are congruent.
Angles E and E' are congruent, and angles F and F' are congruent.
Segments DF and D'F' are congruent, and segments EF and E'F' are congruent.
