Move points J and K so that they lie on the x - axis. [br][br]1) Click and drag Triangle ABC. Change the size of Triangle ABC. What do you notice bout the size and shape of Triangle A'B'C'?[br][br]2) State the coordinates of Triangle ABC and the coordinates of Triangle A'B'C'. [br] A (___,____) --> A' (___,____)[br] B (___,____) --> B' (___,____)[br] C (___,____) --> C' (___,____)[br]3) What changes in the coordinate(s) do you notice when reflecting over the x - axis?[br][br]4) Fill in the blanks.
