An equilateral triangle has three equal sides and an isosceles triangle has at least two equal sides.  Since three is included in the quantity &quot;at least 2&quot;, an equilateral triangle is an isosceles triangle by definition.  Hence it is true that some isosceles triangles are equilateral triangles.
