Answer:
Option D.
Explanation:
A student used a compass and a straightedge to bisect angle ABC in the given figure.
We need to find the statement that best describes point S.
To bisect the angle ABC, the construction stps are:
1. Place the compass on B and draw arc PQ.
2. Now place the compass on P, then draw an arc.
3. After-that without changing the compass, place the compass on Q, then draw an arc that intersect the arc at S.
It means
QS = PS
Hence, the correct option is D.
