Please someone help me, if you don't know the answer don't comment at all. Preston says the sequence of transformations that maps triangle ABC onto triangle DEF is: rotate it 180 degrees about the origin, and then translate it up 7 units.

Chanel says the sequence of transformations that maps triangle ABC onto triangle DEF is: reflect it across the x-axis, then reflect it across the y-axis, and then translate it up 6 units and left 1 unit.
Part E
Now look at Chanel’s sequence. How does a reflection across the x-axis change the coordinates of a shape?

Part I
How does a translations 6 units up and 1 unit left change the coordinates of a shape?

Part K
Whose sequence proves triangle ABC is congruent to triangle DEF? Why?
