WebFor any triangle ABC, let s = 12 (a+b+c). Then the radius r of its inscribed circle is r=Ks=√s(s−a)(s−b)(s−c)s. ... the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is a triangle center called the triangle's incenter ... WebApr 2, 2016 · The incircle of a triangle A B C touches A B at point P and has radius equal to 21 .If A P = 23 and P B = 27 ,then find the sum of the digits in the perimeter of the triangle A B C. We know that inradius = r = Δ s ,where Δ = area of the triangle and s = semiperimeter. Let the incircle touches side A B at P, B C at Q and A C at R.
WebThe incircle touches the sides of the triangle ABC and OP ⊥ BC,OQ ⊥ AC,OR ⊥ AB. i) Now arc RQ subtends`∠`QOR at the centre and `∠`QPR at the remaining part of the circle. ∴ `∠`QPR = `1/2` `∠` QOR. ⇒ `∠`QPR = `1/2 xx120°` ⇒ `∠` QPR = 60° WebProve that if the incircle of triangle A B C touches side B C at D and the A -excircle touches side B C at D ′, then the midpoint of B C is the midpoint of D D ′. This is an interesting property that I discovered when doing a few problems but the solutions didn't prove it.
