Think you’ve got sharp eyes? Here’s a puzzle that tricks 90% of solvers: a hand-drawn circle sliced into wedges, plus the words “CAREFULLY” and “How many triangles 90% failed.” It seems simple, but the real triangles aren’t all in the circular diagram. Can you spot them? Don’t rush—small details hide big surprises. Read on for a step-by-step breakdown that reveals every triangle in the drawing and the text. See if you beat the odds and join the 10% who get it right!

A Fun, Mind-Bending Challenge

Here’s a deceptively simple drawing that 90% of people get wrong—can you figure out how many triangles are hidden in the image below? At first glance, you’ll see a circle divided into eight slices and the words “CAREFULLY” and “How many triangles 90% failed.” But don’t be fooled by the obvious! Hover your eyes over every detail and see if you can spot them all before reading on.

Common Pitfalls to Watch For

• Counting Only the Slices: Many solvers assume each wedge in the circle is a triangle—but that’s only part of the story.
• Overlooking Text Elements: It’s easy to ignore the letters and words surrounding the drawing, yet they hold clues.
• Rushing the Scan: When you speed through, you miss the subtle shapes hiding in plain sight. Slowing down and examining each component is key.

Step-by-Step Breakdown

Let’s reveal the five triangles one by one:

The “A” in “CAREFULLY”

• At the very top of the page, the capital letter A contains a perfect triangle in its negative space.

Three Triangles at the Circle’s Center

• The circle is divided by one horizontal line and four radiating spokes. In the very middle, these lines intersect to form three small triangles.

The “A” in the Word “TRIANGLE”

• Finally, look at the printed word “Triangle” below the drawing. Its capital A also hides one more triangle.

Adding them up gives you 5 hidden triangles in total!
