Answer:
The correct option is A) Always.
Step-by-step explanation:
Consider the provided statement.
If RS = ST then point S is always the midpoint of RT
The midpoint is the point which divide a line segment into 2 equal parts or the midpoint is equidistant from both the ends,
The midpoint also bisects the segment.
As it is given that RS = ST that means the point S divides the line segment RT into 2 equal parts.
For example refer the figure 1:
Hence, the correct option is A) Always.
