Respuesta :

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.

Length of CD

Distance between (1,-3) and (5,-3)

  • 5-1
  • 4units

Rotation means no change in size

So C'D' is also 4units
