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.
Yes
A triangle with side lengths of 3, 4, and 5 inches is a scalene triangle.
That's a scalene triangle.
The length of the hypotenuse of a right triangle with legs of lengths 6 and 8 inches is: 10 inches.

A triangle cannot have four lengths!
The length of the hypotenuse of a right triangle with legs of lengths 6 and 8 inches is: 10 inches.
No.
Yes.
Because all side lengths are different, it must be a scalene triangle.
A perimeter of a triangle is the sum of all three lengths on the sides.
Nope, honey, that's not gonna work. A scalene triangle has three sides of different lengths, so having two sides that are the same length ain't gonna cut it. You need three different side lengths to make that scalene magic happen.
The dimensions of the scalene triangle could be 7 by 5 by 3 inches
