Select the correct description of the mirror image of a clock face showing the time 3:00 when a vertical mirror is placed on its right side at line MN.
- AA
- BB
- CC
- DD
Solution & Step-by-step Explanation
When a vertical mirror is placed on the right side of a clock face:
1. The vertical line passing through 12 and 6 acts as the axis of symmetry. Any horizontal direction is inverted (left becomes right and right becomes left).
2. At 3:00, the minute hand points straight up at 12 (on the vertical axis, so it stays unchanged) and the hour hand points directly right at 3.
3. In the mirror reflection, the hour hand pointing to the right (3) will be horizontally inverted to point directly to the left (9).
Therefore, the mirror image of the clock will display the time as 9:00.
