segment rt lies on the coordinate plane and is rotated 90 degrees, then reflected across the y-axis. what is the change in the segment's length? question 1 options: a. it is 90 times as long. b. it is the same length. c. it is twice as long. d. it is half as long.

B It is the same length.

Step-by-step explanation:

Due to transformations, If you both rotate and reflect a segment it will still remain the same...

R' and T' is created if you do either on a coordinate plane.

Working on it on paper:

Lets create a problem...

"Triangle XYZ is reflected across a coordinate grid what happens to the length and variables?"

It stays the same length and the variables turn into X' Y' Z'.

With this evidence its safe to say the correct choice is B.
