Math Problem Statement

Which triangle is labeled as a right triangle?

Solution

To solve this problem, we need to identify which triangle in the options is a right triangle. A right triangle is a triangle in which one of the angles is exactly 90°.

Steps to Determine the Right Triangle:

  1. Check the Pythagorean Theorem: The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides:

    c2=a2+b2c^2 = a^2 + b^2

  2. Apply the Pythagorean Theorem to each of the given triangles to determine if any of them satisfies the equation.

Analyzing Each Triangle:

  • Triangle A:

    • Sides: 13, 12, 5
    • Check: 132=122+5213^2 = 12^2 + 5^2
    • 169=144+25169 = 144 + 25
    • 169=169169 = 169 (This is a right triangle)
  • Triangle B:

    • Sides: 8, 15, 17
    • Check: 172=152+8217^2 = 15^2 + 8^2
    • 289=225+64289 = 225 + 64
    • 289=289289 = 289 (This is also a right triangle)
  • Triangle C:

    • Sides: 7, 24, 25
    • Check: 252=242+7225^2 = 24^2 + 7^2
    • 625=576+49625 = 576 + 49
    • 625=625625 = 625 (This is another right triangle)
  • Triangle D:

    • Sides: 10, 6, 8
    • Check: 102=82+6210^2 = 8^2 + 6^2
    • 100=64+36100 = 64 + 36
    • 100=100100 = 100 (This is a right triangle as well)

Conclusion:

  • All triangles listed (A, B, C, D) satisfy the Pythagorean Theorem and are thus right triangles. The correct answer is all of the above triangles are right triangles.
