Answer: no
Step-by-step Explanation: If the sum of the squares of two sides of a triangle is equal to the square of the third side or a² + b² = c², then the triangle is right.
In this problem, we're given a triangle that has
sides with lengths of 11, 13, and 17.
Let's plug these lengths into the pythagorean theorem.
(11)² + (13)² = (17)² or 121 + 169 = 289.
Since 121 + 169 ≠ 289, this is not a right triangle.
