Answer:
Let's see if it holds true for these side lengths:
- The square of 6cm is 36cm².
- The square of 12cm is 144cm².
- The square of 14cm is 196cm².
Now, let's add the squares of the two shorter sides:
36cm² + 144cm² = 180cm²
As you can see, the sum of the squares of the two shorter sides is not equal to the square of the longest side (14cm²). Therefore, 6cm, 12cm, and 14cm do not form a right triangle.
