He has to draw arcs through both points and then arcs that stem from those arcs created in the first step.

The guest is correct

 

See this image

 

 

Since  AB  = AC

AD = AD

BD  = CD

 

Then by SSS   triangle BAD is congruent to triangle CAD

The angle BAD   = angle CAD

So   angle ABC is bisected
