What happens here

The presenter introduces three new wooden boards: two 12-inch boards and one 17-inch board. He then successfully arranges these boards to form a closed triangular shape, demonstrating that their lengths satisfy the Triangle Inequality Theorem (12 inches + 12 inches = 24 inches, which is indeed greater than 17 inches).

Goal: Visually demonstrate a valid triangle using lengths that satisfy the theorem

than the third side. So, 5 + 6 less than 24, 12 + 12 equal. So, let's try our next one. So, now we got a 17-in and a 12 and a 12. Let's see if this works. And obviously this will work because 12 + 12 is larger than 17. Whether you're building braces, framing, or just trying to learn something new, always remember that your two shortest sides have to add up to greater than
