Question

Line segment AB is shown on a coordinate grid:
The line segment is rotated 270 degrees counterclockwise about the origin to form A'B'. Which statement describes A'B'?
A'B' is parallel to AB.
A'B' is half the length of AB.
A'B' and AB are equal in length.
A'B' is greater than twice the length of AB.

Answer 1

A'B' and AB are equal in length because a rotation does change the length of a line segment it only changes it's position on the graph.

Answer 2

The answer is C.) A'B' and AB are equal in length.

This is true because a rotation doesn't change anything besides the position of the triangle, polygon, or in this case a line. And also I just the quiz and got it correct.
