Line segment EF is shown on a coordinate grid:

A coordinate plane is shown. Line segment EF has endpoints negative 3 comma 2 and negative 1 comma 2.

The line segment is reflected about the x-axis to form E'F'. Which statement describes E'F'?

E'F' and EF are equal in length.
E'F' is half the length of EF.
E'F' is greater than twice the length of EF.
E'F' and EF are perpendicular.

Answer:

E'F' and EF are equal in length.

Explanation:

A 'reflection across the x-axis' is a type of rough transformation.

Rough transformations are types of transformations where the pre-image and image do not change their size, and therefore congruent to each other.

The x-coordinate in a pre-image would remain the same, but the y-coordinate would become the opposite.


(x,y)\rightarrow(x,-y)

E'F' and EF should be equal in length.
