# User talk:Gamma

Welcome to ProofWiki! Since you're new, you may want to check out the general help page. It's the best first stop to see how things are done (next to reading proofs, of course!). Please feel free to contribute to whichever area of mathematics interests you, either by adding new proofs, or fixing up existing ones. If you have any questions please feel free to contact me, or post your question on the questions page.

Here are some useful pages to help get you started:

• Recent Changes - To keep up with what's new, and what's being added.
• Main Page talk - This is where most of the main discussions regarding the direction of the site talk place. If you have any ideas, please share them!

Cheers, Cynic

## Pythagoras's Theorem

Can you prove that if $\triangle XYZ \sim \triangle X'Y'Z' \Longrightarrow \frac{(XYZ)}{(X'Y'Z')}=\frac{XY^2}{X'Y'^2}=\frac{h_z^2}{h_{z'}^2}=\frac{t_z^2}{t_{z'}^2}=...$?

If so, please do. Thanks a lot. --Cynic-----(talk) 01:22, 29 December 2008 (UTC)

Hey, thanks for putting up some proofs! Don't forget to sign talk pages when you write a comment. See the help page for howto. Thanks! --Joe 01:37, 31 December 2008 (UTC)

## Page reference

When you want to link to another page, you can just put it inside double square brackets. Like [[Stewart's Theorem]]. --Joe 16:30, 31 December 2008 (UTC)

## Length of Internal Bisectors
