Can the numbers 24,32,40 be the lengths of three sides of a right triangle?
Naddika [18.5K]

Answer:

Yes

Step-by-step explanation:

using pythagorus theorum:   a^{2} + b^{2} = c^{2}

24^{2} +32^{2} =  1024+576

                        =   1600

40^{2} = 1600

thus, it can be concluded that these lengths can be the sides of a right-angled triangle.
