What would be a sequence of transformations that would take triangle [i]ABC[/i] onto triangle [i]A'B'C'[/i]? [br]Explain how you know the image of [i]A[/i] coincides with [i]A'.[/i]
Translate B onto [i]B'[/i], and then rotate until the image of A lands on [i]A'[/i]. Rigid transformations keep the distances the same, so the image of A is on ray [i]B'A'[/i] at a distance of [i]B'A'[/i]. That means the image of [i]A[/i] has to land on [i]A'.[/i]
