Answer:
Right triangles:
5) 0.75, 1, 1.25
6) 18, 80,82
Not right triangles:
1) 5,5,√50
2) 6.5, 3.2, 7.8
3) √2, √3, 4
4) 12, 13, 20
Step-by-step explanation:
Right triangles: (for right triangles the Pythagorean theorem is true)
6) 18² + 80² = 82²
6724=6724
5) 0.75² + 1² = 1.25²
1.5625 =1.5625
1) 5² + 5² ≠(√50)²
1250≠ 50
2) 6.5² + 3.2² ≠ 7.8²
52.49≠60.84
3) (√2)² +(√3)² ≠ 4²
5≠ 16
4) 12² + 13² ≠ 20²
313 ≠ 400
5, √50, 5
18, 80, 82
0.75, 1, 1.25
5, √50, 5 ⇒ √5²+5²= √50
18, 80, 82 ⇒ √18²+80²=82
0.75, 1, 1.25 ⇒ √0.75² + 1² = 1.25
All the others are not satisfying √a²+b²=c condition
