To determine if the triangle with sides 15, 10, and 12 is a right triangle, we can use the Converse of the Pythagorean Theorem. According to this theorem, a triangle is a right triangle if the square of the length of the longest side is equal to the sum of the squares of the lengths of the other two sides.
First, we identify the longest side. The sides are 15, 10, and 12, so the longest side is 15.
Next, we calculate the squares of the sides:
-
Square of the longest side:
\( 15^2 = 225 \) -
Sum of the squares of the other two sides:
\( 10^2 + 12^2 = 100 + 144 = 244 \)
Now we compare the two values:
- The square of the longest side is 225.
- The sum of the squares of the other two sides is 244.
Since \( 225 \neq 244 \), we conclude that the triangle with sides 15, 10, and 12 is not a right triangle.
So the correct response is: No, because 244 is not equal to 225.
