alleryThe face of a human being has a plane of symmetry running where?
AAcross the eyes
BDown its centre
CAlong the jaw
DAround the head
Answer & Solution
Correct answer: B. Down its centre
1. A plane of symmetry splits a body into mirror halves.
2. On a human face it runs vertically down the centre, between the eyes.
3. A plane across the eyes, along the jaw or around the head would not give mirror halves.
