For the polygons below, select all the reflections that carry the figures onto themselves. A rectangle with opposite vertices, across the diagonal, labeled A and B. Parallelogram C D E F, with C and E at opposite vertices, and D and F at opposite vertices. All four sides of the figure are congruent. A regular heptagon with consecutive vertices G and H labeled. Side K is opposite vertex H, with J at one end of side K.

A. Reflect the rectangle across a line through A and B.
B. Reflect the parallelogram across a line through C and E.
C. Reflect the parallelogram across a line through D and F.
D. Reflect the regular heptagon across a line through G and J.
