Prove theorem 6-4.
given: m ab = m cd in circle p
prove m< 1 = m< 2
see picture

Hence Proved  m∠1 = m∠2.

Step-by-step explanation:

We need to Prove m∠1 = m∠2

Solution:

               Statement                                                    Reason

     m arc AB = m arc CD                                             Given

Now we know that by theorem;

"Central angle is always equal to arc subtended by it."

    m∠1 = m arc AB, m∠2 = m arc CD                     Central angle (∠) = m arc

Now substituting the values in above step we get;

          m∠1 = m∠2                                                      Substitution

Hence Proved  m∠1 = m∠2.
