Answer:

Yes

Explanation:

Follow the rule:

a² + b² = c²

c is always the hypotenuse, or the longest side (25).

b and a are usually interchangeable.

Let:

a = 15

b = 20

c = 25

Plug in the corresponding numbers to the corresponding variables in the equation:

a² + b² = c²

(15)² + (20)² = (25)²

Simplify. First, solve the powers, then add:

225 + 400 = 625

225 + 400 = 625

625 = 625

Yes, the set 15, 20, 25, represent a right triangle.
