Answer:

The image of $D$ must lie on the ray $BA$ , since ray $BA$ is antiparallel to ray $BD$ . That is, the angle between both rays is 180 degrees.

Step-by-step explanation:

Let be $D'$ the image of $D$ such that $D$ is rotated 180 degrees counterclockwise with $B$ as center of rotation.

$D'$ must lie on the ray $BA$ , since ray $BA$ is antiparallel to ray $BD$ . That is, the angle between both rays is 180 degrees.
