Question

In the figure given above there are maximum ........... number of triangles that can be identified
(Note:- DO NOT include spaces in your answer)

Answer 1

Correct Answer: 12

Count by size instead of listing triangles ad hoc.

1. Count the smallest triangles formed at the nearest line intersections.
2. Count the medium triangles made by combining two adjacent smallest triangles.
3. Count the largest triangle formed by the outer boundary of the whole figure.
4. Add the three counts together to get the maximum total.

This size-by-size count gives 12 triangles in total.
