Question

Line segment EF is shown on a coordinate grid:
The line segment is rotated 180 degrees counterclockwise about the origin to form E'F'. Which statement describes E'F'?

E'F' is perpendicular to EF.
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.

What do you think it is?

Answer 4

I think it's A

Answer 5

Well.. Read this In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.

Answer 6

& also think can there be any difference in the lengths of EF & E'F' ?
