Basically, from one midpoint to another.

So, what does that tell you about other parts of the triangle?

Answer 4

They're equal?

Answer 5

Which parts are equal?

Answer 6

The side angles

Answer 7

Well, it does say some things about angles. But more importanly, the midpoint part says something about the sides and how they are split up.



The sides with | are equal to each other. The sides with || are equal to each other. On your triangle, what does that mean for the HJF stuff?

Answer 8

They're both equal to each other

Answer 20

Well, it is about terms. Midsegment in this case. Once you know the full meaning of the term, it is easier.

That regentsprep site has great explanations... but bad navigation. However, if you google:
site:www.regentsprep.org midsegment
Then you can find their definition pretty easy.

I'll give it a try, thanks.
