How do you you make 5 triangles out of 9 toothpicks?

To make 5 triangles using 9 toothpicks, you can create a structure by forming a tetrahedron. Start with 6 toothpicks to form a triangular base and three additional toothpicks that connect each vertex of the triangle to a central point above, forming three more triangles with the base. This configuration allows you to utilize all 9 toothpicks effectively to create a total of 5 triangles.
