How many triangles are there in the figure corresponding to Q.80 in image_146f63.png?
- A6
- B10
- C11
- D12
Solution & Step-by-step Explanation
To find the total number of triangles in the figure from Q.80 of image_146f63.png, we can count them systematically by breaking them down into single regions and combinations of multiple adjacent regions:
1. Single-region triangles: Counting the smallest individual component triangles that do not contain any internal lines.
2. Two-region triangles: Combining two adjacent regions to form larger composite triangles.
3. Multi-region triangles: Combining three or more smaller regions, including the largest main overarching triangle itself.
By systematically enumerating all these individual and composite triangular shapes, the total number of triangles is found to be 12.
