Question

Can 3,4,7 make a possible right triangle?

Answer 1

Let's see by using the Pythagorean theorem.

3 and 4 are legs. 3 is the shortest leg.

7 is the hypotenuse.

The theorem states that:

a² + b² = c²

a = 3

b = 4

c = 7

3² + 4² = 7²

9 + 16 = 49

25 = 49 (Incorrect)

So it is not possible for 3,4,7 to be a right triangle.
