Solution:
Here, we have an image and count total number of triangles.
First we will count small triangles as below:
So, we have a 6 triangles.
Next, we will combine small triangles and count them as below:
So, here the triangles are: BAD, BAE, BAF, CAE, CAF, DAF, HBE - a total of 7 triangles.
Thus, in all we have 6 + 7 = 13 triangles.
Hence, we have 13 triangles in all.
