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.
I TRULY HOPE that all of you have read section 4-1 and are now card-carrying members of Club CPCTC. If you come to class without a solid understanding of the reading, you will quickly fall behind.
BTW, Our club song is "Corresponding Parts of Congruent Triangles are Congruent" - which is sung to the tune of "It's beginning to look a lot like Christmas."
So, if you believe (DO YOU BELIEVE?!?!) in CPCTC, then you believe in question #10a that trngl-STO cngrnt trngl-KRO, yes? (Please note the importance of the stated order of the vertices STO & KRO - this was emphasized in the reading).
So, if you believe that trngl-STO cong trngl-KRO, then which angles are cong to which angles?
Well then, what can you call segment RT relative to segments ST & RK? A transversal, yes? Furthermore, what can you say about the relationship of angle-KRO and angle-STO (btw, in this diagram, you can call them angle-R and angle-T)? Got it yet?? Let me know!
No, using the symmetric property does not constitute a different answer. HOWEVER, what you are probably missing is that in addition to identifying angle congruence, you can indentify SEGMENT congruence as well... ca-peeesh??
As for your previous (good) question, when you start comparing triangles (or polygons for that matter) it is VERY IMPORTANT to name the corresponding vertices in proper order.
I'm going to bed (ya know, that beauty sleep thing again... I know you guys wonder how I can look THAT GOOD every day!)... keep the questions coming, I'll look at them in the morning before class..
How is line segment ST || line segment RK?
ReplyDeleteAs shocking as it may be,

So I'm off by a few syllables on the song... it's poetic license, ok? Plato & Socrates would approve!
ReplyDeleteOh ok, now I understand.
ReplyDeleteif tri< ABC is cong. to tri< FGH is <A cong. to <F and <B cong to <G etc?
ReplyDeleteoh nvrm its in the reading. corres. <s of 2 cong. tri<s are cong. to each other its in the reading and its #8. its a definition
ReplyDeleteis it allowed for #9 to use reverse sayings? like <L is cong. to <F and <f is cong. to <L as two separate answers?
