...described on OX as diameter. Thiit this is so is seen when the triangles OXll' and OPR are compared. These triangles have two sides of the one equal to two sides of the other, each to each, and the angle at 0 between them common to both. Hence the angle OR'X is equal to the angle ORP which is...
