Sometimes, isosceles just means that two sides are the same.

An isosceles triangle is any triangle with 2 sides that are equal in length. So every equilateral triangle is a special case of an isosceles triangle since not just 2 sides are equal, but all 3 are. But every isosceles triangle is not equilateral, because you can have 2 sides of equal length and a third side that is either longer or shorter than those 2 sides. For example, if the triangle is a right-angle triangle and the two sides that meet to make the right angle are the same length, then the 3rd side would be longer than those two. Hope that helps.

sometimes. this is analagous to the question "is a rectangle a square or is a square a rectangle?"
The answer is in how the shapes are defined. An equilateral triangle has 3 sides of equal length, and an isosceles only requires 2 sides of equal length. So obviously an equilateral triangle is a type of isosceles triangle which happens to have the 3rd length equal to the other 2. An isosceles triangle however is not a type of equilateral triangle because it is easy to find a counter example when it is not true.

The definition of an isosceles triangle is that it has AT LEAST two congruent sides, and since an equilateral triangle has AT LEAST two congruent sides
an isosceles triangle is SOMETIMES an equilateral triangle

an equilateral triangle is always an isosceles triangle because it always has two side that have the same leanth on the other side the isosceles triangle dosnt have to have 3 equal sides so the answer is sometimes

Maybe, if all the angles = 60°
More appropriately, all equilateral triangles are isosceles.

never.
an isosceles triange has exactly two congruent sides whereas an equilateral triangle has three congruent sides.

it is a triange with two equal sides and the third is different. equilateral is obviously one with the same for each side so theyr not the same

Hey there!
The answer to your question is never. Isoceles triangle is a triangle, with two sides of equal length. An equalateral triangle is a triangle, with three sides of equal length.

never because an equallaterial has all equal sides and isociles has 2 same and 1 diffrent sides.
