Which describes how to construct a duplicate angle?

A. Draw a starter ray, set the compass at length AB, place the compass at C, mark point D.

B. Draw a starter ray, locate point C on starter line; draw an arc with center at A that intersects both
sides of the angle; using same radius, draw an arc with center C; label points B, D, and E, draw an arc with radius BD at center E; label intersection F; draw ray CF.

C. Draw a starter ray, duplicate the line segment on the ray, duplicate each angle using the two
endpoints of the line segment as vertices of the angles: extend sides of angles.

D. Draw a starter ray, locate point C on starter line, set the compass at length AB, draw an arc with center C all the way around.
