A triangle has side lengths of 13 feet, 18 feet, and 13 feet. What kind of triangle is it? Choices: (A)equilateral (B)isosceles but not equilateral (C)scalene

Identify sides equality: Identify if the triangle has any equal sides. Since two sides are 13 feet each, it indicates that these sides are equal. Determine triangle type: Determine the type of triangle based on the side lengths. Since two sides are equal and one side is different, this is characteristic of an isosceles triangle. Check for equilateral: Check if all sides are equal which would make it equilateral. Since one side is 18 feet and the others are 13 feet, it is not equilateral. Confirm not scalene: Confirm it's not a scalene triangle, as scalene triangles have all sides of different lengths. Here, two sides are the same.
