What theorem would lead to this conclusion? Why is this impossible? Suppose < Step 2. AC AB. Then what could you conclude about m and m ABC BCA? What theorem would lead to this conclusion? Why is this impossible? Step 3. If we know that cannot be equal to and that cannot be less than AC AB AC AB, what alternative is left? Explain.
