inscribed Circle radius=area of triangle/semi perimeter
r= √3/4a^2/(3a/2)
=a/(√3*2)
r= √3/4a^2/(3a/2)
=a/(√3*2)
ethan1:
why semi perimeter And why we are dividing it with Area
it would be very helpful If you will explain
there are four center in every triangle in-centre,circum-centre, centroid, Ortho center
in-centre is the point intersection of three Angle bisector of a triangle
8 type of formula is used to find a area of triangle
area=inradius*semi perimeter
