Hello!
By definition, the intercept of the 3 bisectors, within a triangle is the Incenter. So let's get started, by tracing three bisectors.
In the triangle PQR::
- Use a compass, open its legs with a little more than half of  . Place the needle point in the vertex of P. Mark! . Place the needle point in the vertex of P. Mark!
- Do the same, placing the needle point in Q, following  direction. Mark direction. Mark
- Repeat it with the other triangle's line segment, namely:
 
    4.Trace with a ruler, from each intersection point a line. You'll trace three lines then.
     5. Place the compass' needle point in this intersection point, (inside the triangle) with a hinge up to the triangle side, draw the circle inscribed.
