Answer:

B) A reflection over L maps point C to point A and maps point D to itself. Reflections preserve distances, so D must be equidistant from A and C.

Explanation:

We are given the following information:

  • Line
    \ell is the perpendicular bisector of segment
    \overline{\sf AC}. This means that line
    \ell passes through the midpoint of segment
    \overline{\sf AC}, and it is perpendicular to
    \overline{\sf AC}, splitting
    \overline{\sf AC} into two equal parts.
  • D is any point on line
    \ell.

We want to prove that point D is equidistant from points A and C, which means that the distance from D to A is the same as the distance from D to C. To do this, we can consider a reflection over line
\ell.

When we perform a reflection over a line, it transforms objects on one side of the line to corresponding objects on the other side of the line while preserving distances along the line of reflection.

So, when we perform a reflection over line
\ell:

  • Point C is mapped to point A.
  • Point D remains where it is.

Now, since reflections preserve distances along the line of reflection, the distance from D to A must be the same as the distance from D to C. In other words, D is equidistant from A and C.

Therefore, the correct answer is option B:

  • A reflection over
    \ell maps point C to point A and maps point D to itself. Reflections preserve distances, so D must be equidistant from A and C.

To summarize, line
\ell is the perpendicular bisector of segment
\overline{\sf AC}. When we reflect over line
\ell, it swaps the positions of A and C while keeping point D in its place. Since reflections preserve distances, D must be equidistant from the new positions of A and C, which are the same as the original positions of A and C. Therefore, D is equidistant from A and C.
