True.

An equilateral triangle is a special type of triangle where all three sides are equal in length. In an equilateral triangle, all angles are also congruent (equal) because the sum of angles in any triangle is always 180 degrees. Therefore, in an equilateral triangle, all three angles are equal.

By definition, an isosceles triangle is a triangle that has at least two sides that are equal in length. Since an equilateral triangle has all three sides of equal length, it automatically fulfills the criteria of an isosceles triangle.
