√(s − a)(s − b)(s − c)(s − d) (Fig. 8.12). Prove this re- sult as follow


Post Merge: Just now

14.   Show that the diameter D of the largest circle that can be in- scribed in a right triangle with legs a and b and hypotenuse c is given by D = 2ab/(a + b + c). (This is a generaliza- tion of problem 16 of chapter 9 of the Nine Chapters, which uses the specific 8-15-17 triangle.)
