I am sorry for late. I was not here!

When I am thinking, I concluded that: - If the triangle was rotated (-180 or +180, whatever) about any one of its three vertices (A or B or C), the image would touch the pre-image at only one point, no more. -If the rotation point was F, the image would touch the pre-image at no any point. - BUT if the rotation point was E or D, the image would touch the pre-image at more than one point. Try it yourself! I hope I helped you, @princeevee. +Sorry again for being late!
