Triangle pat has been reflected over the x-axis. which of the following best describes the relationship between the x-axis and the line connecting p to p′?

1 they share the same midpoints.
2 they are diameters of concentric circles.
3 they are perpendicular to each other.
4 they are parallel and congruent.

3. They are perpendicular to each other.

Step-by-step explanation:

Triangle PAT has been reflected over the x-axis to form triangle P'A'T'.

The rule of this reflection is

The x-axis has the equation

Segment PP' contains all points with the same x-coordinates, this means this is vertical segment (see attached diagram).

since horizontal and vertical lines are prependicular, then x-axis and line connecting points P and P' are perpendicular to each other.
