What is the total number of triangles in the given diagram?
Show answer & explanation
Correct answer: B
Explanation
To find the total number of triangles, we systematically count them based on their composition:
• Single-region (small) triangles: 8
• Triangles formed by combining 2 parts: 5
• Triangles formed by combining 3 or 4 parts: 3
• Large triangles: 2
Total number of triangles = 8 + 5 + 3 + 2 = 18.
Hence, the correct option is (B).
