Explanation:

Step1: Recall triangle definitions

An equilateral triangle has all three sides equal. An isosceles triangle has at least two sides equal. A scalene triangle has all sides of different lengths.

Step2: Analyze side lengths

The given triangle has side lengths \(7\), \(17\), \(17\). Since two sides (\(17\) and \(17\)) are equal and the third side (\(7\)) is different.
