Geometry isn’t just for the classroom — it’s taking over social media in the form of this deceptively simple-looking triangle puzzle. At first glance, it may look like just a few triangles within a box, but the more you look, the more you realize… this isn’t as easy as it seems.

This viral brain teaser challenges your visual perception and attention to detail. The goal? Count how many individual triangles exist in the shape above.

The challenge is structured within an irregular quadrilateral divided by multiple lines, creating intersecting shapes. It’s not just about spotting the obvious — you’ll need to identify:

Small individual triangles

Overlapping triangles

Larger combined triangles

Hidden shapes formed by multiple lines

Experts say puzzles like these can improve spatial reasoning and cognitive flexibility. Plus, they’re just plain fun!

🔢 So what’s your guess — 10 triangles? 12? Maybe even more?
