Triangles D E F and D prime E prime F prime are connected at point E. Triangle D E F is rotated about point E to form triangle D prime E prime F prime.

dilation
reflection
rotation

Rotation.

The figure is obtained by rotating triangle DEF about point E to get D'E'F'. A rotation (about E by the appropriate angle) is a rigid motion that maps each vertex and preserves the SSS congruence.
