### the Isosceles Angle Theorem, and 4ABEis congruent to 4ADEby SAS so 6 BAEis congruent to 6 DAE. E, being on both! BDand! DB, is on the same side of line ADas Band on the same side of line AB as Dby two applications of the Ray Theorem. So Eis in the interior of 6 BAD= 6 BAC. So! AEis an angle bisector for 6 BAC. I think this is what the author has in mind but Im not convinced that we arenâ€™t

- 346/ ANGLE BISECTORS IN A TRIANGLE Angle Bisectors in a Triangle I. F. Sharygin In this article, we have collected some geometric facts which are directly or tan- gentially related to the angle bisectors in a triangle. These results vary from easy lemmas to serious theorems, but we will not classify them; rather, we will just number them. Every statement that occurs without a proof is
