Question

The line segment is rotated by 270 degrees counterclockwise about the origin to form C'D'. Which statement describes C'D'? C'D' is 4 units long. C'D' is 8 units long. C'D' is parallel to CD. C'D' is half the length of CD.

Answer 1

Answer:

• A. C'D' is 4 units long

Step-by-step explanation:

According to the graph, CD is 5 - 1 = 4 units long.

Rotation doesn't change the length of the segment, so C'D' = CD = 4 units.

Correct choice is A.
