We all love riddles and train our brains, and it’s a good choice. Are you ready to wake up and face this puzzle?

Here comes the challenge. It’s not proper math, but I remember our geometry teacher gave us a similar problem back in school. This may seem easy at first but you will quickly realize it is not as easy as it looks.

Below, there is a picture – and the question is: how many triangles are in it?

How many did you find? The answer will be below the next picture.

The answer is revealed below but doesn’t cheat by peeking!

A

B

C

**ANSWER**

It is important to think a little outside the box to figure this one out.

The correct answer is 13 triangles, that is, option C.

First, there are nine small triangles, that’s the easiest part.

Then we have three larger triangles that are made up of four small ones.

Finally, we have a large one that composed of all the other triangles.

9 + 3 + 1 = 13
