The incentre is equidistant from—

aall three vertices
ball three sides
conly two sides
dthe circumcentre and centroid

ব্যাখ্যা

The incentre is the point where the angle bisectors meet, and each bisector keeps points equally distant from the two sides forming the angle. Consequently the incentre is equidistant from all three sides, which is why a circle centred there touches each side.
