Understanding Right Triangles
A right triangle is defined by its right angle (90 degrees) and adheres to the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. This is expressed as:
a² + b² = c²
where \( c \) is the length of the hypotenuse, and \( a \) and \( b \) are the lengths of the other two sides.
Testing the Given Sides
To determine if 2.5 cm, 7.5 cm, and 7 cm can form the sides of a right triangle, we will evaluate different combinations:
  • Combination 1: 2.5 cm, 7.5 cm, and 7 cm

    • Assuming 7.5 cm is the hypotenuse:
    • 2.5² + 7² = 6.25 + 49 = 55.25
    • 7.5² = 56.25
    • Not a right triangle.

  • Combination 2: 2.5 cm, 7.5 cm, and 2.5 cm

    • Assuming 7.5 cm is the hypotenuse:
    • 2.5² + 2.5² = 6.25 + 6.25 = 12.5
    • 7.5² = 56.25
    • Not a right triangle.

  • Combination 3: 7 cm, 2.5 cm, and 7.5 cm

    • Assuming 7.5 cm is the hypotenuse:
    • 2.5² + 7² = 6.25 + 49 = 55.25
    • 7.5² = 56.25
    • Not a right triangle.



Conclusion
None of the combinations of 2.5 cm, 7.5 cm, and 7 cm satisfy the Pythagorean theorem, meaning they cannot form the sides of a right triangle.
