If a, b and c are the sides of a triangle where a = 12, b = 5 and c = 13 is this a right triangle ?

yes

Step-by-step explanation:

To determine if the sides form a right triangle.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then triangle is right.

longest side is c = 13

13² = 169

a² + b² = 12² + 5² = 144 + 25 = 169

Since c² = a² + b² = 169

Then the sides form a right triangle
