Answer:
a. P
d. S
e. T
Explanation:
A reflection is a transformation that flips the side of a line a point is on.
Reflection of Points Across a Line
When a point is reflected across a line, it maintains the same distance from the line, but on the opposite side. This means that if a point is on the negative side, it will be flipped onto the positive side and vice versa. The line a point is reflected across is known as the line of reflection.
This means that the points P, S, and T will move across the line m.
Reflection of Points on a Line
However, if a point is on the line of reflection, it will not move. Since a reflection does not change the distance a point is from a line, it does not affect points on the line. If a point is zero units from the line, it will still be zero units from the line after reflection. Thus, it these points do not move.
This means that points Q and R will not move after reflection.
