Strategy guide

1.Systematically count triangles by size: start with smallest, then combine to find larger ones;
2.Trace each triangle with your finger or visually to ensure all sides are connected properly;
3.Check intersections where lines cross - these often create additional small triangles.

Common mistakes

1.Counting only the large obvious triangles and missing smaller ones formed by intersecting lines;
2.Forgetting to count triangles that share sides with other shapes in the diagram;
3.Overcounting by including shapes that look triangular but aren't complete triangles in the puzzle.
