How to draw the incircle or incenter of a triangle?

If the bisectors of the three angles of a triangle are drawn, they will intersect at a point inside the triangle. At the point of intersection, draw a perpendicular to any side of the triangle from that point. Now if we draw a circle from the point with a radius equal to the length of the perpendicular drawn on the arm, we will get the incircle. The center of which is the incenter.
