What equilateral triangles are isosceles?

Answer 1

No.

Answer 2

An equilateral triangle is a special type of isosceles so an isosceles triangle can not be described as an equilateral triangle so, any equilateral triangle can be an isosceles triangle but an isosceles triangle can not be an equilateral triangle

Answer 3

An equilateral triangle is one where all three sides are of equal length.

An isosceles triangle has at least two sides of equal length.

If the three sides of a triangle are equal, it is necessary that if any two of the sides are chosen they are also of the same length. Thus equilateral triangles are isosceles. This does not imply, though, that all isosceles triangles have to be equilateral.

The confusion comes because we usually stick to calling equilateral triangles equilateral because that description tells us more about the triangle than the fact that it is incidentally also isosceles, just as we also refer to squares as squares even thought technically are also in the sets of geographic figures referred to as rectangles and rhombuses respectively, i.e all squares are also rectangles and rhombuses..

Answer 4

No because an equilateral triangle has 3 equal sides but an isosceles triangle has only 2 equal sides

Answer 5

No, none of the equilateral triangle will be isosceles.

Answer 6

All of them are, isosceles triangles top 2 sides are equal. Equilateral triangles have 3 equal sides and satisfy the requirements of isosceles.

Answer 7

Not exactly because an equilateral triangle has 3 equal sides whereas an isosceles triangle has only 2 equal sides.

Answer 8

false
