Use the image to answer the question. David constructed ∠ABC and needs to double the angle by constructing a copy of the angle using ray BA as one of the sides of the new angle. He has constructed an arc, as appears in the image. What next step must he take to construct a copy of the angle using ray BA ? (1 point) Responses He must measure the distance between point B and the arc using a compass. He must measure the distance between point cap b and the arc using a compass. He must measure the distance between point B and point C using a compass. He must measure the distance between point cap b and point cap c using a compass. He must draw an arc that intersects the larger arc by placing the pointed end on point A . He must draw an arc that intersects the larger arc by placing the pointed end on point cap A. He must measure the distance between point A and point C using a compass. He must measure the distance between point cap A and point cap c using a compass. Skip to navigation

To construct a double angle at ∠ABC using ray BA as one side, David needs to measure the distance between point B and point C using a compass. This will allow him to then recreate that same distance from point A to create another arc that will intersect with the larger arc he has already made. Consequently, the correct response is:
He must measure the distance between point B and point C using a compass.
