Can you guess how many triangles there are in the picture?
For this brainteaser, you'll need to be quick as we're only giving you 20 seconds to find out how many triangles there are in this picture. It's trickier than it sounds, especially when the pressure to find the right answer starts to crank up as the clock ticks down to zero...
Thanks for taking part. Did the number of triangles surprise you? Or did you get the answer pretty much straightaway?
Whatever number you came to, it's always good to get the gray matter going from time to time. These sorts of exercises encourage logical reasoning and can be plenty of fun to do when you want to break up the day.
