Solution: The triangle has three sides of equal length, and therefore it is an equilateral triangle. All equilateral triangles have angle measures of 60º, 60º, and 60º. Therefore, this triangle can also be classified as equiangular or acute. Answer: The triangle is equilateral, equiangular, and acute.
