Virtupets, Inc. has decided to create a new toy called the **Pretty Pretty Princess Prism**! This toy has no nefarious purposes at all whatsoever, who told you that?!

A 2-dimensional concept drawing* of the "toy" was leaked earlier this week and can be seen below.

**Ooohhhhhhh... shiny.**

*not to scale

For no reason at all, you decide to figure out **how many triangles there are in the drawing, not counting half of the triangles that are one-half the size of the largest triangle.** Then you submit the number below!

Enter ** just** the number. Adding anything else will disqualify you!

Anyone know the answer?

ReplyDeletedid you even try to figure it out?

ReplyDeletei put 6 but dont know if its right. lol

ReplyDeleteI think it is seven

ReplyDeletei got like 28 but i dont think its correct

ReplyDeleteI've counted 31 triangles so far but have probably missed a couple

ReplyDeleteIt's 9 you bunch of tools !!!

ReplyDeleteI believe it is 47 because it found it one a diff site and that is what they got

ReplyDelete"not counting half of the triangles that are one-half the size of the largest triangle"

ReplyDeleteDon't forget that, guess most people will do that when looking up answers ;)

Its 4 or 5

ReplyDeletenot counting half of the triangles that are one-half the size of the largest triangle"

ReplyDeleteDon't forget that, guess most people will do that when looking up answers ;)

if this is right..then its alot easier then i thought...

How are you getting such low numbers? I got 38 on my first count.

ReplyDeleteI got like 23 :P

ReplyDeleteFirst of all, remember that a triangle is not necessary an equilateral triangle! So those of you with low numbers are probably making that error.

ReplyDeletei'm at 40 so far

ReplyDeleteits a matter of counting

ReplyDeletei got 31.... it says dont count half the triangles that are 1/2 the size of the largest. the whole triangle is the largest and there are 2 that are half the size.. so you would only have to take away 1 triangle :P ITS A TRICK TO MESS WITH YOU..

ReplyDeletethere are 6 triangles that are half sizes.... therefore only 3 of them would count

ReplyDeletethere are more than 2 that are half the size...

ReplyDelete39? :S

ReplyDeleteThere's only 6 triangles that are half the size of the biggest triangle, NO MORE, NO LESS.

ReplyDeletehow many do you think have it by now

ReplyDeleteTheres 40

ReplyDelete44

ReplyDeleteI counted 33 triangles minus the 1 triangle that is one of the two halves of the largest triangle.

ReplyDeleteSo my answer was 32. But I doubt its right.

classic neopets. easy lenny one week, crazy difficult lenny the next *_^

There's only 6 triangles that are half the size of the biggest triangle, NO MORE, NO LESS.

ReplyDelete^

I agree with this

there is a "not to scale" note at the bottom. so how do you guys know for sure that some of the triangles are half the size of the largest triangle? We can not assume that the drawing is for a isosceles triangle, right?

ReplyDeleteI think the "not to scale" refers to Sloths actual device, but the drawing proportions would remain accurate.

ReplyDeleteLook, draw a triangle on paper using three differnt colored ink pens for each side and make it large enough so you can make the folds. Then cut it out. Let's say you used blue ink, red ink and green ink to make each side.

ReplyDeleteYou can fold the triangle in half with blue on the bottom, or with green on the bottom or with red on the bottom = 6 different triangles that are HALF the size of the big triangle.

See what you missed when you slept through geometry?

The answer is 44 GOSH

ReplyDeletehttp://www.castleviewuk.com/answer_-_how_many_triangles.html

ReplyDeleteThat should help! :)

@E What you are talking about is only for eq lat triangle.....

ReplyDeleteIt doesn't say anywhere that it's just equilateral triangles..

ReplyDeleteIt should be 44. If you use the site provided above and subtract 3 (there are 6 triangles that are half the largest triangle, and half of THAT is not counted. 6 divided by 2 = 3 so you subtract 3 from the total number)

ReplyDeleteThere are 47 triangles in total, and when you subtract 3, TADA. You get 44 :)

How on earth are u people counting up to 30 triangles? Maybe its not as difficult as ur making it seem. I sure as hell dont see 30 triangles

ReplyDeleteThe correct answer is 44.

ReplyDeleteAnonymous two above this comment is correct. It is exactly what I got and it is the answer. Anyone that can't see at least 30 triangles should probably be a little worried... there are 47 total.

ReplyDelete@E What you are talking about is only for eq lat triangle....

No, if you were to make the folds, (in essence bisecting the large triangle, they are not eq lat triangles. See the URL that was posted. It makes the answer obviously simple to see.

"not counting half of the triangles that are one-half the size of the largest triangle"

ReplyDeletedoes size mean area or shape

the line down the middle given 2 that are half the area

but there are 4 smaller triangles in the middle that i think are half the size (half length and height)

It says not to scale, and it also says that you shouldn't count the triangles that are one-half the size of the largest one. Perhaps this scale is half the size of the actual toy, so all of the triangles in this figure are half the size of the actual one.

ReplyDeleteI got 0.

???

ReplyDeleteHow did you get 0?

Given your reasoning, even if all triangles were half the size of the original toy, you would still have to count half the triangles. There is NO way you would end up with 0.

ReplyDeleteI would just ignore the not to scale part, I dont think it has anything to do with the riddle. I got 35.

ReplyDelete41

ReplyDeleteAnd they mean not to scale of the toy... not the triangles

ReplyDeleteIt's 31 triangles...

ReplyDeleteGiven your reasoning, even if all triangles were half the size of the original toy, you would still have to count half the triangles. There is NO way you would end up with 0.

ReplyDeleteIt makes more sense now. I was just trying to think logically, because whenever I read riddles, I try to find a hidden way around it. That's why I got 0, but thanks anyway. :)

Just ignore the not to scale part. It is normally used to prevent a reader from utilizing what could be a bad drawing from the writer as a clue to solve the problem. It is not applicable when measurements/numbers are not given. If it's not to scale and you re-draw the diagram above you should only be worried if you can fit the given information with a different drawing which is not possible here. Regardless of however you draw it, it will look exactly like the diagram above.

ReplyDeleteJust use the URL I posted earlier, it makes the answer a lot easier to figure out.

What they should do is should accept 44 or 45 as the answer since they didn't specify if "half the size of the original triangle" meant area or dimensions. But they'll probably only pick one. *sigh* Hope I went with the right one.

ReplyDelete^They did.... "not counting half of the triangles that are one-half the size of the largest triangle"

ReplyDeleteIs the largest triangle not the original? Illiterate kids.

I got 27. I thought that the outline was the biggest triangle, which would mean that there are 2 that are 1/2 the size of the biggest, which would mean you add an extra if you don't find the 2 that are 1/2 the size of the biggest, and if you did you would only count one. (I hope that makes sense.)

ReplyDelete48 total triangles. 6 triangles(remember to count two at each corner of the whole triangle)are half the largest...so the answer is 48-3===== 45

ReplyDeleteBy the way...

ReplyDeleteIt says,"you decide to figure out how many triangles there are in the drawing"

IN THE DRAWING...

It doesn't matter what scale the drawing is to or what size the actual toy is. These are red herrings.

i counted 28 but i think theres more

ReplyDeleteThere are 47 triangles, 6 of which are half the size of the largest triangle so the answer is 44.

ReplyDeletethe answer is 44 (already minusing the three halves)

ReplyDeleteIt is 81 triangles you

ReplyDelete39 triangles minus 3 equals 36

ReplyDeletethere are 36 triangles for the answer

http://rg03.wordpress.com/2007/09/20/counting-triangles/

ReplyDeletehas the answer also explains it 47 minus 3 = 44

44 was the answer. Got a trophy :D
