How many triangles do you see?
Only one percent of the population can spot all of the triangles in this mind-bending illusion, according to a viral TikTok by a user called Hectic Nick.
Nick shared the illusion and it quickly went viral, racking up 1.6million views and over 135k comments.
“It sounds simple, but it’s not easy,” he teased. The large, primary triangle was immediately apparent, as were some smaller triangles toward the top, but the rest of the image is filled with other shapes.
The number of triangles contained in the image is eighteen.
If you struggle to count them all, treat the lines in the image as a grid, and construct triangles of varying sizes row by row and column by column.
