(The circle is tangent to the three sides of the triangle.) (not to scale)

(Pythagoras)

(square and two kites) (found previously)

Supplementary: What is the radius of the circle touching the three sides of the triangle?

Supplementary: What is the radius of the circle touching the three sides of the triangle?

Supplementary: What is the radius of the circle touching the three sides of the triangle? But what about the other answer?

But why did algebra bring up this answer?
