Answer:
Yes
Step-by-step 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.
