To determine whether the given sets of measurements can describe the lengths of the three sides of a right triangle, we can use the Pythagorean theorem. The theorem states that for a triangle with sides of lengths \(a\), \(b\), and \(c\) (where \(c\) is the longest side), the following must hold true:
\[ c^2 = a^2 + b^2 \]
Let's analyze each set of measurements:
-
[4m, 5m, 6m]
- Identify the longest side: 6m
- Check if \(6^2 = 4^2 + 5^2\): \[ 36 = 16 + 25 \implies 36 = 41 \text{ (False)} \]
- Conclusion: Cannot be the sides of a right triangle.
-
[63 in, 16 in, 65 in]
- Identify the longest side: 65 in
- Check if \(65^2 = 63^2 + 16^2\): \[ 4225 = 3969 + 256 \implies 4225 = 4225 \text{ (True)} \]
- Conclusion: Could be the sides of a right triangle.
-
[29 in, 20 in, 21 in]
- Identify the longest side: 29 in
- Check if \(29^2 = 20^2 + 21^2\): \[ 841 = 400 + 441 \implies 841 = 841 \text{ (True)} \]
- Conclusion: Could be the sides of a right triangle.
Summary of Results:
- 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]
