Answer:
Skew (option d).
Step-by-step explanation:
Skew lines are the lines that do not intersect with each other. These lines exist in different planes and hence do not intersect each other and they are also not parallel. For skew lines to exist, 3 -d planes are required.
Here, the lines e and c are skew lines because they do not intersect each other and are lying on different panes. They are also skew line because the planes are co-planer,
Hence, the lines e and c are skew lines.

Answer:
The image of OH is ON.
Step-by-step explanation:
Te figure GIKMPR is a regular hexagon. The number of vertices of a regular hexagon is 6. The central angle between any two consecutive vertices is 60 degree.
The dashed line segments form 30 degree angles.
If we rotate the hexagon 180 degree about O, then the each point shifts to 6th place from its original place.
Since we rotate the hexagon 180 degree about O, so the image and preimage lies on a straight line. Because a straight line make angle of 180 degree.
The line OH and ON lies on a straight line therefore the image of OH is ON.
