Average Values of Triangles [PDF]

open access: yesFundamental Journal of Mathematics and Applications, 2020
The average area and perimeter of triangles defined by three random points on the circumference of a unit circle are already known. In this paper, we calculate the average value of the inradius along with its variance. We also consider the average area, inradius and circumradius of triangles of unit perimeter.
