What could I say as the reason for the proof on #29 pg 276? I'm really not sure.. I think you told me in class, but I forget! I think it was theorem 2-5 or something, but you said you didn't want us "naming" the theorems by exact number, so what could the "wordy" reason be?
Even though you said this was coming up in the next unit (but we sort of already learned this with transversals & such) would we be allowed to use "Alternate Interior Angles Theorem" to prove <ATG & <SGT congruent? Because GS and AT are ||...
Is the test going to be any harder than the Chapter Test in the book? Because I really couldn't find anything that troubled me in the Chapter Test. Is there something special that might trouble me that could be on the test?
A problem# would be helpful, but if you have two parallel lines cut by a transversal... gosh, that's been on your toolbelt and in your G.B. for a while, yes?
Dear Lucky 13... Alt Int Angles is the ticket for that problem... not sure I understand your comments about the next unit... if you have a defn, postlt, thm or crllry on your toolbelt... just use it.
Sorry, Mr.C! I've been SO busy today and I haven't had time to color the logo! I'll try to color it tomorrow after school & give it to you Friday morning in homeroom.. Is that okay?
I have a question about about #5-2... I'm confused on #33.. I really don't know what to do on #33, after stating the Given. I thought about saying for 2) "P is equidistant from A and B" but I don't know what the reason would be for that...
I'm really confused on #4 pg 304. I'm pretty sure it has to do with something like the Third Angles Postulate or similar, but I can't come up with a straight-out answer..
I don't know where to start on #17.. I don't see how the 2 segments are related, the ones it is asking you to solve for. I would understand if it was the perpendiculars to the sides from the angle bisector but the two sides seem unrelated to me.
I'm still a little confused on how to construct an inscribed circle.. for #21 it is asking you to do both, and I achieved the circumscribed circle, but after watching this video: http://www.mathsisfun.com/geometry/construct-triangleinscribe.html
I still don't know what to do after bisecting the angles... help! Could we review this.. Some how? Or could Mr.C make a handy video?
I'm not really understanding the question asked on #29.. I'm pretty sure it's false, but I don't know how to provide a counterexample.. I tried to draw another triangle with points P & Q & R but couldn't find a different triangle with the same possibilities.. I'm probably just doing something wrong.

ReplyDelete#29 shows an isosceles triangle with a perp line drawn from the vertex angle to the base.
ReplyDeleteWe can say that the perp line form rt angles (defn of perp), so we can say that we have two rt ∆s (by defn a rt ∆ contains one right angle).
The hyp's of both ∆'s are cong (given) and the perp line is cong to itself (reflx prop), so the ∆'s are cong due to HL.
helpful??
Yes! Helpful!
ReplyDeleteI'm doing the Chapter Test now so more questions may come.. :)

ReplyDeleteSort of learned? Eh???
Dear Trouble-Free,
ReplyDeleteSo you're lookin' for trouble, eh? Or are you troubled that you're not troubled? There's a country western song in there somewhere... Ryan? Julia?
Ain't got no trouble troublin' me,
I gotsk me a test in Geome-tree
... I'm feelin' it... could be a hit!!
Mr. C.
I'm troubled that I'm not troubled!
ReplyDeleteAnd for #13, it was on the Chapter Test on pg 277.
ReplyDeleteDear Lucky 13... Alt Int Angles is the ticket for that problem... not sure I understand your comments about the next unit... if you have a defn, postlt, thm or crllry on your toolbelt... just use it.
ReplyDeleteSomebody lookin' for trouble? (he asked with a scowl)... I'll give you some trouble!
ReplyDeleteOk! Sorry, my question was a little unclear, but you answered it. Thanks!
ReplyDeleteI might have some more questions coming! Sorry!
ReplyDeleteSorry, Mr.C! I've been SO busy today and I haven't had time to color the logo! I'll try to color it tomorrow after school & give it to you Friday morning in homeroom.. Is that okay?
ReplyDelete^That above message was from Lotta. :)
ReplyDeleteNo questions! I'm still surprised! I normally have questions!
ReplyDeleteThe logo can wait until the weekend... but I would like to wrap the contest before the winter break...
ReplyDeleteOk, thanks!

By the way, can I give you my logo on Friday?
ReplyDeleteI'm going on the field trip tomorrow.

ReplyDeleteI have to go to bed! I'll check the answers after school tomorrow! Thank you!
