Congruent Segments

[color=#000000]The following applet illustrates what it means for segments to be classified as [b]congruent segments.  [br][br][/b]Interact (play around) with the applet below.  Be sure to move the locations of the black points around each time [i]before[/i] you drag the slider!  [br][br]Then respond to the prompts that follow.[/color]
Respond in your daily notebook.
[color=#000000][b]1.1[/b][br][br]A) What transformations have we learned about thus far?  List them.[br][br]B) What transformations are used in the applet above to take one segment to the other?[br][br]C) Make a biconditional statement in 'if-and-only-if' form defining what it means for two segments to be classified as [b]congruent[/b].[/color]
