Smaller triangles = 3
Triangles formed with combination of 1 triangle and 1 quadrilateral = 3
Triangles formed with combination of 2 triangles and 2 quadrilaterals = 2
Triangles formed with 2 triangles = 2
Triangles formed with 3 triangles = 1
Larger triangles = 1
Thus, total triangles = 3 + 3 + 2 + 2 + 1 + 1 =12
