Answer:

  • 1, 2, 4, 6, 8

Step-by-step explanation:

Right triangles have a property of:

  • c² = a² + b², as per Pythagorean

Let's try each group:

  1. 25² - 24² = (25+24)(25-24) = 49 = 7² - yes
  2. 41² - 40² = (41 + 40)(41-40) = 81 = 9² - yes
  3. 74² - 69² = (74 + 69)(74 - 69) = 143*5 ≠ 24² - no
  4. 65² - 52² = (65 + 52)(65 - 52) = 117*13 = 13*9*13 = 39² - yes
  5. 19² - 15² = (19 + 15)(19 - 15) = 34*4 = 17*8 ≠ 8² - no
  6. 61² - 60² = (61+60(61 - 60) = 121 = 11² - yes
  7. 68² - 60² = (68 + 60)(68 - 60) = 128*8 ≠ 30² - no
  8. 58² - 42² = (58 + 42)(58 - 42) = 100*16 = 40² - yes
