Step-by-step explanation:
The triangles are the same size, so we know there's no dilation.
That leaves two steps: rotation and translation.
It's possible to do this in one step: 180° rotation about the point halfway between any point and its image. In this case, the point (1, 0).
1) Rotate 180° about (1, 0)
However, if we assume we want to rotate about the origin, the steps are:
1) Rotate 180° about origin
2) Translate 2 units right
Or:
1) Translate 2 units left
2) Rotate 180° about origin
I don't know what the options are in the drop-down menus, so choose whichever is available.
