10, 24, 26 form a right triangle
a^2 + b^2 = c^2
10^2 + 24^2 = 26^2
100 + 576 = 676
676 = 676

Just square the three numbers, they must satisfy this
a^2 + b^2 = c^2 where c is the largest side
the square of the smallest number + the square of the next number = the square of the largest number
7^2 + 9^2 = 12^2
49 + 81 = 144
130 = 144 not a right triangle because they are not equal
10^2 + 24^2 = 26^2
100 + 576 = 676
676 = 676 This will form a right triangle
Check the rest...

pythagoras, a^2+b^2=c^2, where c is the longest side
check all:
7, 9, 12 = no
10, 24, 26 = yes
18, 20, 27 = no
8, 11, 19 = no

10 24 26
Pythagorean Theorem
c² = a² + b²
√c² = √(10²) + (24)²
√c² = √100 + 576
√c² = √676
c = 26

10,24,26 because 10 squared+24 squared=26 squared

You have to check which of these triples
satisfy a² + b² = c².
The only one that does is 10,24,26
since 10² = 100
24² = 576
26² = 676.
