Triangle ABC and its image Triangle A'B'C' are graphed above.[br]Play around with the pre-image by moving its vertices to new locations. [br]Notice the angle measurements of the pre-image and image.[br]Play around with the vector by changing its direction and magnitude.[br][br]What do you notice about the triangles as you move the vertices and change the translation? What do you wonder? Make a conjecture about translations and congruent shapes.

Is the statement sometimes, always, or never true?[br][br]The pre-image and image of translations are congruent.
