Which statements are true about reflections? Check all that apply.

An image created by a reflection will always be congruent to its pre-image.
An image and its pre-image are always the same distance from the line of reflection.
If a point on the pre-image lies on the line of reflection, the image of that point is the same as the pre-image.
The line of reflection is perpendicular to the line segments connecting corresponding vertices.
The line segments connecting corresponding vertices are all congruent to each other.
The line segments connecting corresponding vertices are all parallel to each other.

Let's evaluate each statement related to reflections:

  1. An image created by a reflection will always be congruent to its pre-image.

    • True: Reflections preserve distances and angles, which means the image will be congruent to the pre-image.
  2. An image and its pre-image are always the same distance from the line of reflection.

    • True: By definition, the image point is located directly opposite the pre-image point at the same distance from the line of reflection.
  3. If a point on the pre-image lies on the line of reflection, the image of that point is the same as the pre-image.

    • True: If a point is on the line of reflection, it remains unchanged in the reflection.
  4. The line of reflection is perpendicular to the line segments connecting corresponding vertices.

    • True: The line of reflection is always perpendicular to the line segments that connect corresponding points (or vertices) in the pre-image and image.
  5. The line segments connecting corresponding vertices are all congruent to each other.

    • True: Since reflections preserve distances, the segments connecting corresponding points (matching pre-image and image points) will be the same length.
  6. The line segments connecting corresponding vertices are all parallel to each other.

    • False: The line segments connecting corresponding vertices are not necessarily parallel; they can converge towards or diverge from the line of reflection depending on the orientation of the pre-image.

So, the true statements are: 1, 2, 3, 4, and 5.
