NO but every Equilateral triangle is an Isosceles triangle. That is the difference .
Isosceles triangles have only 2 sides the same length.
Equilateral have ALL 3 sides the same length which means that they must have 2 sides the same length, so they are a very special case of an Isosceles triangle.
That is why they have a special name - Equilateral meaning 'all sides equal'. The word lateral is a reference to the word length.

No, it is not.
There are two definitions of isosceles, one of which defines it as a triangle with exactly two equal sides, which excludes equilateral triangles. The other definition is a triangle with two or more equal sides and therefore is inclusive of equilateral triangles.
Isosceles triangles usually have two congruent sides, but the rule is that they actually have at least two. That means that they can also have a third congruent side. That means they are both equilateral and isosceles*, which I personally think is way too confusing, but that's how it works.Example: A triangle has angles of 60 degrees, 60 degrees, and 60 degrees. It is both isosceles and equilateral.*I think that equilateral triangles are actually a type of isosceles triangle, so that if you're asked on a math test, for example, whether a triangle is scalene, isosceles, or equilateral, you'd say equilateral.No, Isosceles is two equal sides, although an equilateral triangle CAN be an isosceles triangle. And Angles of an isosceles triangle are not known (given) - simply two equal sides.Three, like every other triangle.
Every triangle has three angles that total 180o. In an equilateral triangle, there are three 60o angles.
180 Degrees.In an equilateral triangle, each angle and side is 60 degrees.there is 180 degrees in every triangle
