Video Brain Teaser #13

[XDCherryXDBlossomXD]

I got this one rite ^_^

[gemadiktuz]

haha #LOL haha

i got most of them

[ghfreakwierdo123]

these are making me feel so dumb!!!!

[videomathtutor]

@ghfreakwierdo123 Don't feel bad. Just take your time, and keep trying! There are MANY Brain Teasers here for you to do.

[Skaterboy692]

Thats wrong. You said 8 equilateral triangles.2 are bigger then the others. Duh.

[videomathtutor]

@Skaterboy692 They are still equilateral triangles. I did not say they had to be the same size.

[sk8rlt]

i keep getting 7 equalateral triangles

[syafiq210]

equilateral mean ALL the sides the same not ALL the triangles the same. LOL

[armadillodude]

devious -.-

[frelongty]

hmm... confusing video... i thought u said 8 equilateral.. meaning ALL of them have to be the same....

[dryman2]

If you don't know what equilateral means, it means that all sides are the same.

[Teh1337man]

Re: frelongty

If he said IDENTICAL, that means ALL of them haz to be the same size, but he said just "..8 EQUILATERAL TRIANGLES.."

[bluedust80]

@frelongty equilateral means all sizes the same

[videomathtutor]

@bluedust80 Equilateral means the sides of an individual triangle are all the same. The triangles themselves may be different sizes.

[bluedust80]

@videomathtutor sorry i didn't mention that also i got alot of your brain teaser right.

LOL i like the soultion becasue i did the same thing but i did not count the two big triangles

[ChargersFanForLyfe]

6/13 :D

[DoogBoy123456]

Smart.... Smart....

[sfwjy]

i think fastfinger is the ignorant one.

[dalessergod87]

i ve not seen the solution yet, but can somebody type me the challenge or what he says (before releasing the solution ofcourse). i dont get the accent as my mother tounge is not english :p

[MurasakiYugata]

"Here are two equilateral triangles. The challenge now is to rearrange the sticks in such a way as to get eight equilateral triangles."

;)

[DapwnageG]

i got a different answer on this one

[bubbaherc884]

i got it yay!!

[coolboy780]

i got it! woot! 5 stars!

[Christina66771]

i got it right! yay

[spaghettiisFOB]

Holy Chuck Norris I actually got it!

[MeTsMaN09]

woo

[shyla11]

that one was easier then all the others ones, atleast i thought so but i guess it depends

[Indifferent1618]

That was a hard one hah, I wasn't even close

[ikemjeri]

let me guess, through elementary school and high school, you got an A in math class every semester! :P

[videomathtutor]

Close. I didn't start getting straight A's in ALL my subjects until the 4th grade through 12th grade (Yes, I was Valedictorian of my High School class, along with 3 of my siblings).

I did slack off in college as the years went by and my GPA there got so bad, I think it went negative! So I know how both ends of the spectrum feel like when it comes to earning grades.

[Qwubs]

You still shouldn't feel any shame....Valedictorian is VERY hard to achieve.

[videomathtutor]

Well, I read these days it is not that hard. When a school has 40+ Valedictorians, I suspect it practices grade point inflation.

[1FastfingersMcgee1]

they do its through honors classes (5.0 scale) and AP (advanced position [6.0 scale] in which you get college credit) there is still only one validictorian which is the person with the highest GPA

[videomathtutor]

There can be more than one Valedictorian. I read about a H.S. that had 40+ at the same time. That is just wrong.

[1FastfingersMcgee1]

thats probrably one of those expieramental liberal hs that grades all woke subjectively (most likely a's to all students) and have to make everyone feel good by handing out awards like candy or it could be that 40 kids have identical gpa's which could happen

[videomathtutor]

I don't know about that, but I think it is safe to say they teach spelling in that school.

[1FastfingersMcgee1]

nah they stopped spellin tests in 6th grade.. i've never seen a spelling course in hs nice jab at my spelling errors though at least i still have a 3.7 gpa in college and an 1890 on my SAT sooo i dnt see ur point oh and yes its a fact about the high schools there are some out there (ran by liberals) who grade subjectively.. kids were sayin 2+2=5 and they were getting credit look it up jackass

[videomathtutor]

High test scores and GPA are not true indicators of intelligence, as your comments clearly indicate.

Sorry, but by the way you express yourself, you are not a very bright person. It is easy to claim high scores, but you don't show this. I never took the SAT (just the ACT) and my college GPA eventually got so low, I think it went negative, but I like to think I am an intelligent person, and I like to think my writing shows this.

[1FastfingersMcgee1]

dude you are so ignorant im not gonna be writing formally on youtube cmon i type for speed and efficiency here not proper grammer.. you think im the dumb one but at least im passing college with a full ride scholarship. i do agree with you that gpa and test score dont accurately depict inteligence but it is a good standard to go by and you want an example of my writing.. fine i will send you a thank you letter i wrote to the people that provided one of my scholarships

[videomathtutor]

I will let others who read these comments to determine who between the two of us is the "ignorant" one. I did not ask for formal writing, just proper. I type very fast, and yet I don't make many mistakes. I also go back and re-read what I typed before posting, to catch any errors I may have made. It is a good habit to get into.

Oh, I had my share of scholarships too. I am not interested in reading a thank you note your Mommy probably helped you write. Have a nice day.

[CrazyBrooke316]

FastFingers is so ignorant

[ikemjeri]

so if u started slacking off in collage, why did u start making these videos?

[videomathtutor]

The Brain Teasers are made for fun.

[ikemjeri]

do u come up with them, or............?

[videomathtutor]

No, I did not invent these. They are classic Brain Teasers that are probably over 100 years old. I do plan to come up with one or two of my own soon.

[ikemjeri]

where do u find them? just in case i want to do some to my friends or i can show them some of your videos and they would probly be inpressed with either one of them ! :)

[videomathtutor]

I don't remember. I have collected them over the years. The Optical Illusions and "Find the Twin" problems are from a Clip Art collection. Do a search for Nova Development to find online.

[ikemjeri]

i mean do u go on like google or something like that?

[videomathtutor]

No, but you are welcome to do that.

[warriorrabbi]

this one sort of got me, i did the shape but thought the question was 6 triangles lol so i sort of got it right

[BekksRich]

Hey, were you a wizz kid in school by any chance? Nice going. :)

[videomathtutor]

I was a WHIZ kid (note spelling).

[scarysnowman777]

man that one i actually got yay i got 3  7 8 and 10 too but whatever

[mahkah10]

that was the easiest so far for me

[xxSyphenxx]

i was thinking the solution COULD just be how the triangles were.. because mathmatically triangles have 3 sides right? so every time you rotate your head, you see a triangle.. so technically there are 3 triangles in a triangle.. but that cant be the answer because if you take how many triangles are in both triangles that would make 6 and not 8.. But possibly you can rearrange the sticks using the same way im using, but putting a few extra triangles.

Hopefully the poster understands what i mean.

[videomathtutor]

I understand what you mean, but it is not a solution.

[xxSyphenxx]

sadly, yes, its not. :(

[eloisehaunts]

Yay I got it :D

[Felgrand101]

Just a neutral question: are you allowed to make a shape besides the squares that are asked for?

[videomathtutor]

Huh? There are no squares in this problem. You can have other shapes besides triangles, as long as you get the 8 ones I asked for.

[Felgrand101]

Sorry for mentioning the squares. My bad. Of course I meant the triangles. But thanks.

[robertpalacinka]

i got this one :D

[Peace17love]

it was easy....!weird

[Kelvinxiaozhu]

wow!!! u taught me sometin!!! i used to hate math, bt after watchin your teasers, i felt math is fun!!!!

[11NINA112]

good one!

[stuffedXcucambor]

heh, if it wasnt for my flag, i wouldnt have solved this one.

[kellysable]

This is slightly less impressive than the earlier square puzzles since you created incidental polygons in the solution. If you allowed extraneous forms in prior puzzles there would be many more solution models than were intended, I think. Still a cool set of videos though.

[jkmusicvideos]

Exactly what I was thinking.

[95angeleyes]

coooooooooooooooooool

[onegin5511]

oh yeah i see

amd i agree with you, wctje777

[wctje777]

i already thought huh those are only 6 but that is what brain teasers are for, to look behind whats going on
