That "If triangle ABC is rotated 180 degrees" is the hard part.  Rotated about which point, or about which line?  Are you certain you've copied down every bit of the original question?

@mathmale yes i have

In that case, we'll have to make assumptions.  Our answer will be no better than our assumptions.

For example, if we rotate that given triangle about the point C, the result looks like this:|dw:1395272303235:dw|
