Line segment CD is shown on a coordinate grid:

A coordinate plane is shown. Line segment CD has endpoints 1 comma 2 and 1 comma negative 1.

The line segment is rotated 90 degrees counterclockwise about the origin to form C'D'. Which statement describes C'D'?

A) C'D' and CD are equal in length.

B) C'D' is parallel to CD.

C) C'D' is half the length of CD.

D) C'D' is greater than twice the length of CD.

Respuesta :

the answer is A) because the length does not change when it is turned.

When a line is rotated, it must be rotated through a point.

C'D' and CD are equal in length.

Rotation is a rigid transformation.

This means that, when a line is rotated, the image and the pre-image would have the same length.

This means that the length of CD and C'D' are the same.

Hence, the correct option is

(a) C'D' and CD are equal in length.
