摘要: A measuring tool for determining angles at two points of interest, including an elongate arm and protractors, one protractor rotatably mounted each end the arm. Each includes a flat positioning against interest. The angle point interest is angular measurement between flats, respectively. may include attachment sections, sections connected to respectively, L-shaped guide having three connection selectively receiving retaining in various configurations as desired.
