-- both have three angles
-- both have three sides
-- the interior angles of each add up to 180 degrees
-- neither has any side longer than the sum of the other two sides
-- both have at least two equal angles
-- both have at least two equal sides
-- the area of each is half the product of its base and its height
Are isosceles triangle sometimes an equilateral triangle
It can be scalene or isosceles but not equilateral.
An isosceles triangle has at least two congruent sides. An equilateral triangle has three congruent sides. So, an equilateral triangle is a special case of isosceles triangles. Since the equilateral triangle has three congruent sides, it satisfies the conditions of isosceles triangle. So, equilateral triangles are always isosceles triangles. Source: www.icoachmath.com
Yes, an equilateral triangle is also an isosceles triangle. By definition, an equilateral triangle has all three sides of equal length, which satisfies the condition for being isosceles, where at least two sides must be equal. Therefore, every equilateral triangle is inherently isosceles.
Not ... exactly. It would be closer to accurate to say that an equilateral triangle is a special case of the isosceles triangle.All equilateral triangles are (also) isosceles; but most isosceles triangles are not equilateral.

The contrapositive would be: If it is not an isosceles triangle then it is not an equilateral triangle.
No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides

An equilateral triangle has all sides measuring the same and an isosceles triangle has 2 sides congruent, so they are not the same. Every equilateral triangle is also an isosceles triangle, but not every isosceles triangle is an equilateral triangle. Isosceles = at least two equal sides Equilateral = three equal sides

Isosceles has 2 equal sides, but an equilateral triangle, all of its sides are equal.
No. An equilateral triangle is where all three sides of the triangle are equal. An isosceles triangle is where only two of the sides are equal.
No
No.
