What composite transformations could be used to have triangle 1 turn into triangle 2?

Answer:
see below
Step-by-step explanation:
The vertex order has been reversed, so a reflection is involved. The direction of the short side has been changed by 90°, so a rotation is potentially involved. Depending on the precise rotation and/or reflections, translation may be involved.
One potential set of transformations is ...
Another potential set of transformations (shown below) is ...
