Question

Line segment EF is shown on the coordinate grid:A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A line segment EF is shown with E as ordered pair 1, negative 4 and F as ordered pair 5, negative 4.The line segment is rotated by 270 degrees counterclockwise about the origin to form E′F′. Which statement describes E′F′? (1 point)E′F′ is equal in length to EF.E′F′ is half the length of EF.E′F′ is parallel to EF.E′F′ is twice the length of EF.

Answer 1

the initial coordinates of EF are:

`(1,-4),(5,-4)`

then the segment is rotate 270 degrees counterclockwise so:

In a rotation the length do not change so the answer is A) E'F' is equal in length to EF
