Subset means all the elements in it are present in the superset. Then it is called as a subset. It we take equilateral triangle, it possesses the characteristics of isosceles triangle. But isosceles triangle don't(it means isosceles triangle don't have characteristics of an equilateral triangle). Hence, equilateral triangle is subset of isosceles triangle.
