At first glance, the image looks simple: a single large triangle with smaller triangles neatly carved inside it. But don’t be fooled by its clean lines and soft colors. This visual puzzle has been circulating online for years, sparking debates, comment wars, and countless “Wait… let me count again” moments.

So here’s the challenge: How many triangles do you see?

Take a few seconds. Look closely. Count carefully before scrolling.

Most people assume the answer is obvious. It isn’t.

Why This Triangle Puzzle Is So Tricky

Our brains love shortcuts. When we see a familiar shape like a triangle, we tend to focus on the most obvious forms and ignore combinations hiding in plain sight. This image plays with that instinct by layering triangles within triangles—some pointing up, some pointing down, some overlapping, and some formed only when smaller shapes are combined.

That’s why people often get wildly different answers.

• Some see 9.
• Others swear it’s 13.
• A few confidently claim 18 or more.

And here’s the interesting part: the number you see often reflects how you approach problems, not just how well you count.
