At first glance, this simple line‐drawing looks like four triangles stacked on top of each other. But there’s more hiding in those crossing lines than meets the eye. Will you breeze through counting the outlines—or get tripped up by the quieter shapes that lurk between them? In this post, we’ll show you the six triangles you might have overlooked, explain why most solvers stop at four, and give you a foolproof method for spotting every hidden form. Ready to sharpen your attention to detail and master this deceptively easy puzzle? Dive in!

How Many Triangles Can You See?

Have you ever met a puzzle that looks so simple you almost skip over it—only to realize you’ve missed the obvious? Today’s challenge is a prime example: a stack of four overlapping triangles, sketched in a single continuous line, hiding more shapes than you think. If you’re up for a quick mental stretch, take a moment and see how many triangles you can spot before reading on.

Why Most People Get It Wrong

A lot of solvers jump straight to counting the four big outlines and stop there. Others search feverishly for every tiny shape, convinced they’ll uncover dozens, then end up doubting their own eyes. The secret? Balance: focus on each intersection without over-complicating things, and you’ll avoid both undercounting and overcounting.

Step-by-Step Breakdown

The Four Outlines

• Start by tracing each of the four large triangles in a different color. Those are the most obvious shapes.

The Central, Overlapping Triangle

• Next, notice where the three inner lines cross to form one more, smaller triangle right in the middle.

No More, No Less

• There are exactly six: the four obvious ones plus the single, central overlap plus one more that sits between the top and middle outlines.
• Triangle 1–4: The four large, distinct outlines
• Triangle 5: The small triangle created by the top and middle lines
• Triangle 6: The tiny center where all three lines intersect
