What are you noticing about angle C and angle F? Justify why F maps onto C with the reflection described above.
The measures of angle C and F are the same. [br][br]Angle CAB is congruent to angle FDE, so DF will map onto AC since line segments coming from the same point at the same angle will overlap. [br][br]Angle ABC is congruent to angle DEF, so FE will map onto CB since line segments coming from the same point at the same angle will overlap. [br][br]AC and CB intersect at point C, and DF and FE intersect at point F. Since the line segments overlap, their intersection points will also overlap, and F will map onto C.
