Notice that [math]\overline{AB}\cong\overline{DE}[/math] and [math]\overline{BC}\cong\overline{EF}[/math].[br][br]You can move points C and F around.
Make [math]\angle B[/math] larger than [math]\angle E[/math].[br][br]Is AC larger or smaller than DF?
Make [math]\angle B[/math] smaller than [math]\angle E[/math].[br][br]Is AC larger or smaller than DF?
