Triangles...from here to there
Is it possible?
What information would you need to have in order to decide whether it is possible to find a sequence of isometries taking one triangle to the other?
How?
Describe the sequence of transformations (precisely) that will take CD to AE. With each transformation, before you actually execute it, say what you think it will accomplish, why you would want that, and how do you know the transformation will accomplish your goal.
