Incircle radius of triangle formula

WebThese small triangles each have altitude of the incircle radius and total base (across all six small triangles) equal to the perimeter, giving the formula for the incircle radius: $$r_ {\small I} = \frac {A_T} {s} $$ where $A_T$ is the … WebThe area of a circumscribed triangle is given by the formula \frac {1} {2} \times r \times (\text {the triangle's perimeter}), 21 ×r ×(the triangle’s perimeter), where r r is the inscribed circle's radius.
