Segments AB and CD are the ​ (a)   length so they are congruent.

Therefore, there is a rigid motion that takes AB to ​ (b)   .

Apply that rigid motion to the circle centered at A. Since circles are defined as the ​ (c)   a given distance from the ​ (d)   , once the centers and radii ​ (e)   all points on the circles must coincide.

• CD
• set of all points
• center
• coincide
• same
