Scribe #48 I think... Nah... Make it 50.

Well... Long time no Scribe... Hahaha. lol Anyways... Today's Chapter is...

One Regular Day in MATH

Today was a regular day. One day too many. Yet one day too late.

"Hi guys" I said as I walked in the room. I was so happy yet so sad... It's math once again and I feel so bad. It's math. It's math. I am so very pleased. Yet I still rhyme. Get to work... Geez...

Ok. Ok. I looked happily. Three problems on the board. Three problems for we.

(Ok I'll stop I have a Poetry English Assignment... Ok. Hahaha…)

1. Find the values of x and y. Justify your answer.
Hint.… The checkmarks and the o's are congruent.

So we all do the really long way.… Then Mr. K. Tells us to check our dictionary's

ALLWAYS BRING YOU DICTIONARY TO CLASS!!!!

All of your tools are there. lol

So to justify you have to use the Statement/Reason that we learned. He showed us that we could use the Exterior Angle Theorem.

Statement

Angle DEF = 70º

X = 100º

Y = 60º
Reason

Ext. to Triangle ADE

Angle CEF is EXT. to Triangle ACE


Angle ACE is EXT. To Triangle ABC

2. For each pair of triangles write the propeterty which proves the triangles are congruent.



For this one... You had to look in your dictionary for one of four propeteries: SSS, SAS, AAS, or RHL. Which translates to: Side-Side-Side, Side-Angle-Side, Angle-Angle-Side and Right Angle-Hypotonuse-Leg. By the way you are only allowed to use those four propeteries.

Also Mr. K. Taught us the Reflexive Property. Quote "In the reflexive Propetry. You are the same thing as yourself." Basicly If you have a diagram and cut it directly in the middle. One half of the diagram is the same as the other half.

Well in the end you should of got (from left to right, top to bottom) RHL, SSS, NOT CONGRUENT, AAS, SAS, AAS

3. Find two congruent triangles and explain why they are congruent.

This one was a mix of the first question and the second question. So it was really hard. Hahaha...

In the end it ended up like this:
Statement

Line Segment DC is Congruent to Line Segemnt BC

Angle BCD is Congruent to Angle DCB


Line Segment AC is Congruent to Line Segment EC

Triangle ACB is Congruent to Triangle DCB
Reason

Given

Reflexive Propetry

Given

SAS
There was another way... To it to. It involved the top triangles and the congruent angles in the middle

After that he gave us two more questions. What fun. Ha ha ha...

To be honest I really forgot how to do these questions... The bell rang when we were going to review them and I was so lost when I was doing them... Ha Ha Ha?

Anyways... Homework is Excerise 35

AND THE NEXT SCRIBE IS...

It reads Kasia... Hahaha.

By the Way... All Math images are made by EUKLID.

ALSO... I really think there's a PRE-TEST tomarrow... Look's Up...

A great scribe Richard -- excellent detail!

BTW, it's not "reflective" it's reflexive.

And you're not supposed to purposely leave your scribe incomplete -- you don't want to become known as The Incomplete Scrivner. ;-)

Ok ok I'll fix that. (and I'll complete the scribe)

BTW, it's not "Scrivner" is Scriber. I think. Hahaha.

Scrivener ... follow the link. ;-)

I spelled it wrong -- don't tell your English teachers. ;-)

An early scribe worthy of the Hall of Fame. Great Job explaining the concepts in class.

Richy, your explanation here is extremely thorough. It doesn't seem like you could have "faked" this answer-- you have explained your thought process and procedures so thoroughly. Thanks very much for sharing this with a global audience. I am looking forward to showing this to other math teachers, as an example of the ways they should be asking and expecting their students to explain and defend their work as well as their understanding of it.
