**How many triangles?**

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

D

E

**There are a lot of triangles**

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**
