ppose that Z.COE is contained inZ. AOB r times. 2. Then r is the measure-number oi/-AOB referred to Z.COE as a unit. 3. Now the r equal central A which com- pose /.AOB intercept r equal arcs onthe circumference, each equal to CE. 4. .•. r is the measure-number of AB re- ferred to CE as a unit.6.… … I. li Z AOB and Z COE are commensurable. (b) Suppose that Z COE is not contained in Z ^05 an integralnumber of times. The proof is left as an exercise for thestudent. Hint. Some aliquot part of /.COE must be a measure of ZAOB(Why ?) Try i ACOE, \ /COE, etc. II, If Z ^0^ and Z COE are…
