Question

The hexagon GIKMPR is regular. The dashed line segments form 30 degree angles

Answer 1

Answer: The image of of line OH after a rotation of 180 degrees is line ON!!

Answer 2

OJ

Explanation:

Point J is diametrically opposite point Q through rotation center O. Rotation 180° about O makes O the midpoint of Q and its rotated image (J in this case).

Thus the rotated image of OQ is OJ. (Point O is invariant, since it is the rotation center.)
