THE QUESTION
Let’s count the triangles in the image:
- Smallest Triangles: There are 9 small triangles.
- Medium Triangles: There are 3 medium triangles (each formed by combining 4 small triangles).
- Largest Triangle: There is 1 large triangle (formed by combining all 9 small triangles).
Adding them up:
- 9 (small) + 3 (medium) + 1 (large) = 13 triangles.
So, the correct answer is option 5) 13.
