I need a Journal Answer/Written Answer for this one: How do the Triangle-Angle Bisector Theorem and the Angle Bisector Theorem differ?

OpenStudy (anonymous):

U asked this yesterday and I said that I thought they were the same thing.

OpenStudy (anonymous):

Yeah I know. But I don't think they are.

OpenStudy (anonymous):

Why do you think that?

OpenStudy (anonymous):

Someone else mentioned something about the Triangle-Angle Bisector Theorem including an angle bisector.

OpenStudy (anonymous):

http://en.wikipedia.org/wiki/Angle_bisector_theorem

OpenStudy (anonymous):

Hmm. I'll think about it more.

OpenStudy (anonymous):

Your probably right though. lol

OpenStudy (anonymous):

I'll go with your answer. :)

OpenStudy (anonymous):

I'm reasonably sure about it, let's say.

OpenStudy (anonymous):

I'll go with your answer. :)

OpenStudy (anonymous):

Ok

OpenStudy (anonymous):

So you were pretty much correct. The difference is that the angle bisector theorem can be applied to any angle. However when that theorem is applied in a triangle it divides it into two different segments, and the corresponding sides in each of the two segments are then proportional to each other.

OpenStudy (anonymous):

Ah, OK, one is a special case of the other. Thanks for coming back.

OpenStudy (anonymous):

Well I wanted to let you know the answer as well. lol
