Four Triangles Puzzle Hint

Genre: Lateral Thinking Puzzle Rating: 6 - Medium to Hard Source: Unknown
Brain Functions: Creativity / Lateral Thinking Puzzle    Solution

Four triangles have a total of 12 sides. We have only six toothpicks. So each toothpick must be used as the side of two triangles. The illustration shows how five toothpicks can be used to form two triangles by sharing one edge. But you will have to get more creative so that all six toothpicks become shared edges.
