Are these numbers a Pythagorean triple? yes or no

Yes

Step-by-step explanation:

You know if the numbers are in a Pythagorean triple if the sum of the squares of the two smaller numbers is equal to the square of the largest number according to the Pythagorean Theorem: .

Here, a = 15 and b = 20. Let's see if: equals .

15^2 = 225

20^2 = 400

15^2 + 20^2 = 225 + 400 = 625

25^2 = 625

Since 15^2 + 20^2 does indeed equal 25^2, we know that this is a Pythagorean triple.

Hope this helps!
