Answer 1

To determine if a triangle with sides 15, 10, and 12 is a right triangle using the Converse of the Pythagorean Theorem, you need to check whether the square of the longest side is equal to the sum of the squares of the other two sides.

1. Identify the longest side. Here, the longest side is 15.
2. Calculate the squares:
- \(15^2 = 225\)
- \(10^2 = 100\)
- \(12^2 = 144\)

3. Now, check if \(15^2\) is equal to \(10^2 + 12^2\):
\[
225 \stackrel{?}{=} 100 + 144
\]
\[
225 = 244 \quad (\text{False})
\]

Since \(225 \neq 244\), this means the triangle does not satisfy the Pythagorean theorem condition for a right triangle.

The correct response based on the provided options would be:

**No, because 244 is not equal to 225.**
