There is only one triangle. Or two if you count its mirror image as a different triangle.

15 triangles
To determine how many triangles can be formed with sides of lengths 12 inches, 15 inches, and 18 inches, we can use the triangle inequality theorem. This theorem states that the sum of the lengths of any two sides must be greater than the length of the third side. For these side lengths, 12 + 15 > 18, 12 + 18 > 15, and 15 + 18 > 12 all hold true, confirming that a triangle can indeed be formed. Therefore, there is exactly one triangle with the given side lengths.

5*3 - 3*4 = 15 - 12 = 3

There are 13
There are two triangles with sides 9 x 12 x 15 meters. Each of the two triangles is inversely congruent (mirror image) to the other.
