Given that:
It is given that set of numbers can be the lengths of the sides of a right triangle.
Evaluating each set :
#1 :
5, 12, 13
5² + 12² = 13²
25 + 144 = 169
169 = 169
Yes √
#2 :
12, 35, 20
12² + 35² = (20√3)²
144 + 1225 = 400*3
1369 ≠ 1200
No ×
#3 :
5, 10, 5√5
5² + 10² = (5√5)²
25 + 100 = 25(5)
125 = 125
Yes √
#4 :
8, 12, 15
8² + 12² = 15²
64 + 144 = 225
208 ≠ 225
No ×
#5 :
20, 99, 101
20² + 99² = 101²
400 + 9801 = 10201
10201 = 10201
