18 is it…

I came up with 12 and thought nah… there’s more and got 18 but I didn’t count them all. I did maths… I wonder if it was the same maths as pop-sci guy. I counted the first two rows and though hey there’s a pattern.

I didn’t.

I lost count around 68.
When you count the thick and thin blue lines.

I’m working on an uninterrupted line basis. Lines are not crossing the outside border of the large triangle that contains 3 smaller triangles and 6 trapezoids. So I think 3 is acceptable count of circles.

I get 18 - take the topmost tier only - there are 6. Then multiply by 3 layers

One wiseguy counted the triangles in the A’s in the question itself,

Three, three wiseguys!

e.g. How many triangles are there:

There are 385: height * width * (width + 1) / 2

On another note, I sincerely hope the point of this puzzle is not to count the triangles in the A’s. That takes a fun math problem and turns it into:

18, but I’ve done puzzles like this before. :slight_smile:

Well, to be pedantic, the question asks how many I see, so any honest answer is correct.

I consider that to be a valid answer.
