Can you find the exact number of triangles in this image?
It seems complex but it can be broken down into three simple steps as follows:
Step 1: Count the Large triangles
This one is the easiest. It will give 3 triangles. A common mistake here will be to count each vertex as a new triangle thus giving the wrong answer 9. Here's an illustration:
Step 2: Count all the medium triangles.
This is the most complex part. You need to notice here that each vertex has 2 medium triangles and you simply multiply the number of vertices (9) by 2 to get 18 triangles.
Or you could count all of them one by one the old fashioned way as follows:
A little messy yes but you get the point.
Step 3: Count the small triangles.
This will give 9 triangles as follows:
Lastly, you should also count the letter A(3) and the number 4(1) since they include triangles.
This gives a total of : 3+18+9+4=34 triangles.
