Answer: B. E'F' and EF are equal in length.

Step-by-step explanation:

  • A rotation is a kind of rigid transformation which produces the image of same shape and size after rotating it by some degrees .

The rotation has two main properties:-

1. Rotations preserve size ( includes sides and angles).

2. Lines connecting the center of rotation to the pre-image and the corresponding point on the image have equal length.

Given : The line segment is rotated 180 degrees counterclockwise about the origin to form E'F'.

Then, E'F' and EF are equal in length. ( by property 1.)
