How many triangles?

[Manxx]

Haha! So the annual subscription. Is passed over to you - less about 12hours.

… But wait a minute!.. before you go crazily racing through all the thread archives on your free membership… What about the word “triangles” there, does that not also contain a triangle? Did that make it 26 and the subscription back to me?

Bonus or tie-break question. How many squares below?

[MDix]

I saw 30 squares. I am right? hehehe

[Manxx]

I got to 40 so far…

[anon98339083]

I wasn’t given the right answer with the puzzle.

I also got to 40 but was wondering whether there might be more (as there often seem to be, with puzzles like this)?

[Manxx]

There are more if you count oblongs, but they are not squares.
If there are no higher answers then we have to share whatever you have decided to offer as first prize.
I note you didn’t offer an additional annual subscription to BP - was this because you were worried that you might win it?!

I only found 13 triangles.

I was up to 35 squares but I lost my place.

[Manxx]

There is only one point that can be an apex for any triangles i.e. the top point. Then there are four different horizontal base lines you, can use with this apex.

Each of these base lines form 6 different triangles from the apex. 1 using outside lines, 3 separate internal ones and 2 overlapping internal ones.

4 levels X 6 triangles = 24. That is all I found here.

The squares question I guess is still open…

[JimAce]

There are 7 triangles in this picture

[JimAce]

There are 27 squares in this picture

I made it to 20+ triangles then lost my place lol.

Im still at 35 squares.

I really enjoy these kind of optical illusions/quiz/trick questions. Super fun😊

[baemax023]

40 squares.

[fhilpips]

35 is the correct answer. Do not count rectangles and oblongs.

[anon98339083]

There are definitely 40 squares (not counting rectangles/oblongs). The question was whether there might be more than 40.

It seems probably not - I showed it to someone with a maths degree who’s used to these puzzles, and he said 40 immediately. It’s quite a well-known puzzle, apparently.

[wizbrate]

I counted 35 squares as well

[m.k.a]

… 25 triangle @Clint
40 @LaughingCharlie

[m.k.a]

easy how many square in this puzzle
if all bp would come together they cant solve this one ))

[Manxx]

if all bp would come together they cant solve this one

In that case, the answer is 1864.

…so now someone has to prove me wrong, haha!!!

…or does this mean another year added to my jail sentence here on BP!!!

What about the triangles : I found only 21 , although you say there must be 25. That means I should to train my attention, that’s why I won’t count the squares in the last puzzle so far, it’s really a lot of them there

[Falstaff]

What about the triangles

Lol 21 is a wierd number - I can see 24 or 25 depending on the “signature one”, but I’m struggling to find a way of leaving 4 out !
