In the diagram below, AB is the chord of a circle with centre O. OM is perpendicular to AB (meet at a right angle). Look at triangles OAM and OBM. The hypotenuses (OA and OB) are the same, as they are ...
More simply, the angle at the centre is double the angle at the circumference. Angle OGK (\(x\)) = angle OKG because triangle GOK is also isosceles. Lengths OK and OG are also both radii. Angle GOH = ...
Intraarticular fractures of the distal radius were treated successfully with a single volar incision and the insertion of a fixed angle plate. Researchers led by Jorge Orbay, MD, of the Miami Hand ...
