To determine whether the given sets of measurements can be the lengths of the sides of a right triangle, we can apply the Pythagorean theorem, which states that for a right triangle with sides \(a\), \(b\), and hypotenuse \(c\):
\[ a^2 + b^2 = c^2 \]
Let's analyze each set:
1. **63 in, 16 in, 65 in**:
- Check: \(16^2 + 63^2 = 256 + 3969 = 4225\)
- \(65^2 = 4225\)
- **Conclusion**: Could be the sides of a right triangle.
2. **4m, 5m, 6m**:
- Check: \(4^2 + 5^2 = 16 + 25 = 41\)
- \(6^2 = 36\)
- **Conclusion**: Cannot be the sides of a right triangle.
3. **29 in, 20 in, 21 in**:
- Check: \(20^2 + 21^2 = 400 + 441 = 841\)
- \(29^2 = 841\)
- **Conclusion**: Could be the sides of a right triangle.
Now, placing them in the correct boxes:
**Could Be the Sides of a Right Triangle**:
- 63 in, 16 in, 65 in
- 29 in, 20 in, 21 in
**Cannot Be the Sides of a Right Triangle**:
- 4m, 5m, 6m
