In this video I share a pair of formulas to find the radius of a circle inscribed in a triangle ... that were secret to me until very recently. The two formulas are very easy to use, but I show why they are true and where they originate.
The formulas find the length of a circle's radius given the circle is inscribed in a triangle. There are two formulas, one for a circle inscribed in a right triangle and the other geometric formula is for a circle inscribed in a non-right triangle.
