1.
construct the angle bisectors of ∠bac and of ∠abc
2.
intersection point o of the bisectors is the center of the inscribed circle
3.
draw the distance oh from o to any of the sides, let's say ab
oh is the radius of the inscribed circle
1a.
to construct the angle bisector of an angle abc draw a circle with center the vertex b of the angle which intersects the side ab at the point d and the side bc at the point e
then with center in d draw a circle and with center in e and the same radius draw another circle which intersects the first one in the point p
bp is the line bisector of the angle abc
3a.
to draw the distance from a point o to a external line ab draw an arc with center in o which intersects ab in two distinct points f and g
then draw a circle with center f and a circle with center g and the same radius
they intersect outside the triangle in a point k. call h the intersection point of ab and ok
oh is the distance from o to ab
follow the steps on this diagram
and try to do it by yourself
use a huge triangle : )
