Gregory knows that Triangle ABC is reflected onto Triangle A'B'C' . Which statement about the figures is true?

• If Gregory draws the segment with endpoints A and A’, then the midpoint will lie on the line of reflection.

• If Gregory draws the segment with endpoints B and C’, then the midpoint will be on the line of reflection.

• Points A and B are equidistant from the line of reflection.

• AB will be perpendicular to the line of reflection.
