   at two points M and N respectively

2. Open the compass to another width and place its pin at M and draw

    an arc between the two rays YX and YZ

3. Without changing the width of the compass place its pin at N and

   draw another arc intersects the arc from M at point Q

4. Join YQ which is the bisector of angle XYZ

* <em>Now lets compare these steps by the steps of the question</em>

∵ The vertex of the angle ABC is A represented by Y

∵ The rays of the angle AC and AB represented by YX and YZ
