To determine if triangle ABC with sides measuring 39, 15, and 36 is a right triangle, we can use the Pythagorean theorem. A triangle is a right triangle if the square of the length of the hypotenuse (the longest side) equals the sum of the squares of the lengths of the other two sides.
-
Identify the sides:
- a = 15
- b = 36
- c = 39 (the longest side, potentially the hypotenuse)
-
Apply the Pythagorean theorem:
- Check if \( a^2 + b^2 = c^2 \): \[ 15^2 + 36^2 = 39^2 \] \[ 225 + 1296 = 1521 \] \[ 1521 = 1521 \]
Since the equation holds true, triangle ABC is indeed a right triangle.
The correct response is: Yes, because 1,521 equals 1,521.
