Question

Which set of three numbers can be used to make a right triangle? (Use the pythagorean theorem)

Answer 1

Apply the Pythagorean theorem formula:

c^2 = a^2 +b ^2

Where;

c= hypotenuse = the longest side

a & b = the other 2 legs of the triangle

option 1

4,5,6

Replace:

6^2 = 4^2+5^2

36= 16+25

36= 41 NOT A RIGHT TRIANGLE

option 2

3,4,5

hypotenuse = 5 (longest side)

5^2 = 3^2+4^2

25 = 9 +16

25= 25 RIGHT TRIANGLE

Correct option: (3,4,5)
