The ornamental design for a tool for measuringangles at bone joints, as shown and described.
FIG. 1 is a front view of a design for a tool for measuring angles at bone
joints; and,
FIG. 2 is a rear view of the design for the tool for measuring angles at
bone joints.
The tool is planar in shape and preferably transparent where graphic
material is not disposed thereon. Because of its planar shape, all other
views are substantially merely line edges or elongated rectangles.
