From the incentre $O$ , the radius of the incircle is the perpendicular distance from $O$ to—

aany vertex
bany side of the triangle
cthe circumcircle
dthe centroid

ব্যাখ্যা

The incircle touches each side, and the radius drawn to a point of tangency is perpendicular to that side. Thus the inradius is the perpendicular distance from the incentre to any side of the triangle.
