or vertex, of the tri-angle, and find the total number of degrees in the threeangles of each triangle. 4. Take a hne AB oflength 35 millimetres, andwith centres A and B, andradii 45 and 50 miUimetresrespectively, describe por-tions of circles, so thatthey intersect at C. JoinCA and CB. We have… … With the bevel lay off threeangles adjacent to one another,equal to the angles of each tri-angle, in the way indicated in the adjacent figure; and determine the positions of the initial and ^ *- final lines, LM, LK, with respect to one another.
