Concept:Angular distance in surveying is measured using an instrument that determines bearings or angles between survey lines.Explanation:The offset staff and measuring tape are used for measuring short linear distances, not angles.The ranging pole is used for marking or aligning survey lines, not for measuring angles.The prismatic compass is a survey instrument that measures angular distance, which is the bearing of a survey line from north.Therefore, the equipment used for measuring angular distance is the prismatic compass.Answer:D. prismatic compass
