Answer:
5, 12, 13
Explanation:
a² + b² = c²
c is the Hypotenuse (the triangle side opposite of the 90° angle). it is the longest side in a right-angled triangle.
a, b are the legs of the right-angled triangle.
so, they are Pythagorean rules, if the sum of the squares of the 2 smaller numbers is equal to the square of the largest number.
6² + 11² = 13²
36 + 121 = 169
157 = 169
wrong.
5² + 12² = 13²
25 + 144 = 169
169 = 169
correct.
5² + 10² = 13²
25 + 100 = 169
125 = 169
wrong.
