This Blog exists for the collective benefit of all geometry students. While the posts are specific to Mr. Chamberlain's class, any and all "geometricians" are welcome. The more specific your question (including your own attempts to answer it) the better.
You need to look at the corollaries for Thm 8-1 and understand the concept of the geometric mean... it's a little tricky at first, but I have much confidence in you! Once you get it, the proportions just roll off your pencil!
We'll have to go over it in class... I'll try to re-state the corollary below as best I can (I'll use CAPS for the words I add to it)...
When the altitude is drawn to the hypotenuse of a right triangle, each leg OF THE ORIGINAL TRIANGLE is the geometric mean between the hypotenuse OF THE ORIGINAL TRIANGLE and the segment of the ORIGINAL hypotenuse that is adjacent to that leg.
All you can do at this point is stare at the example and try a few problems until you get (hopefully) get it.
Not to worry, we'll put it on the old smartboard tomorrow!
how are we suppossed to solve problems 23-29? Ther are only 2 known measurements. you need 3 to solve!!

ReplyDeletecan you please explain corollary 2 to thrm 8-1 as i do not understand the meaning of it.

u do no5t understand the corolarries or the geometric means at all... basically 16-21 i do not understand
