A pentagon ABCDE is translated north by 40 units to pentagon A1B1C1D1E1. Pentagon A1B1C1D1E1 is then translated east by 150 units to pentagon A2B2C2D2E2. We know the perimeter of pentagon ABCDE is 30 units. Find CC2.

These pentagons are all the same......all corresponding points on A1B1C1D1E1 and  A2B2C2D2E2 are translated the same distance   ( the perimeter is irrelevant)

 

Call  the  center  of A1B1C1D1E1  = (0,0)

Call the center of A2B2C2D2E2  =  (150, 40)

 

The distance CC2  =  sqrt  [ 150^2 + 40^2 ]  ≈  154.24 units
