Explanation:

An equilateral triangle has all three sides equal in length. The given triangle has each side measuring 17 meters, so all three sides are equal. An isosceles triangle has at least two equal sides, but an equilateral triangle is a special case of an isosceles triangle with all three sides equal. A scalene triangle has all sides of different lengths. Since all three sides here are equal, it is equilateral.

A. equilateral
